What Is The Value Of The Missing Angle In The Triangle?A) 156 DegreesB) 66 DegreesC) 142 DegreesD) 150

Answers

Answer 1

Answer:

A

Step-by-step explanation:

We know that the sum of the interior angles of a triangle must equal 180°. So:

[tex](12)+(12)+x=180[/tex]

Solve for x. Add on the left:

[tex]24+x=180[/tex]

Subtract 24 from both sides:

[tex]x=156\textdegree[/tex]

Our answer is A.

And we're done!

Answer 2

Answer:

A) 156 Degrees

Step-by-step explanation:

All angles in a triangle ALWAYS adds up to 180°.

Step 1: Set up equation

12° + 12° + x° = 180°

Step 2: Solve for x

Combine like terms: x° + 24° = 180°Subtract 24° on both sides: x° = 156°

Step 3: Check

All angles should add up to 180°. Plug it in and check.

156° + 12° + 12° = 180°

156° + 24° = 180°

180° = 180°

square root of 1/21 is smallest, then 1/5, then 4.15, then square root of 21

The ansewer is b
The square root of 1/21 means smaller then 1/21 and 1/21 is already the smallest. .20 or 1/5 is the second smallest and 4.5 is less then the square root of 21.

your work
Part A: 5 + 2 = 232 + 13
Part B:5 + 1 = 23% + 13

Answers

Answer:

Part A: 7 = 245

Part B: 6 = 1323/100

Step-by-step explanation:

Part A: Add the numbers 5 and 2 which you get 7 and then you add 232 and 13 which gives you 245

equation version: 5 + 2 = 7

232 + 13 = 245

7 = 245

Part B: In order to convert a precent to a ratio, divide it by 100

23/100

5 + 1 = 23/100 + 13

5 + 1 = 6

23/100 + 13 = 1323/100

6 = 1323/100

Step-by-step explanation:The time taken by car to pass the truck is 1.125 hours

Solution:

A truck enters a highway driving 60 miles per hour a car

The car enters the highway at the same place 9 minutes later and drive 68 miles per hour in the same direction from the time the car enters the highway

Let us first convert 9 minutes to hours

Let the truck covers 'x' m distance in time 't' hour the car will take [t -(3/20)] hour to cover the same distance 'x'

We know that,

For truck : ----------- eqn 1

For car: ------------ eqn 2

From equations (i) and (ii)

Thus the time taken by car to pass the truck is:

Thus the time taken by car to pass the truck is 1.125 hours

Number of miles that marker shows when passes through town= 160 miles.

Number of miles that marker shows currently to John = 115 miles.

We need to find the distance between town and John's current location.

For the problem, we can clearly see that Town is at 160 miles away but when John passes the marker shows 115 miles.

So, it's just the difference between 160 miles and 115 miles.

In order to find that difference, we need to subtract those two numbers.

160miles - 115miles = 45 miles.

So, we could say the distance between town and John's current location is 45 miles.

He'll be able to make 6 shelves.

Step-by-step explanation:

In order to know haw many shelves he can make we need to take the total amount of material and divide it by the amount of material required for each shelve. We have:

total amount = 83 1/2 inches = 83.5 inches

amount per shelve = 12 3/4 inches = 12.75 inches

amount of shelves = total amount/amount per shelve

amount of shelves = 83.5/12.75 = 6.55 shelves

Since he can't make half shelves he'll be able to make 6 shelves and have left over material.

4.5 hours

30 minutes times 9 shelves equals 270

270 minutes translates into 4 and half hours

x=initial deposit amount.

we have to add to the initial deposit amount the incomes and subtract the withdrawal

x+($75.5+$55.25)-($25.15+$18.65)=$210.85

x+$130.75-$43.8=$210.85

x+$86.95=$210.85

x=$210.85-$86.95

Answers

Answer:

The side length is 11 ft

Step-by-step explanation:

The area of a square is given by

A = s^2 where s is the side length

121 ft^2 = s^2

Take the square root of each side

sqrt( 121 ft^2) = sqrt(s^2)

11 ft = s

The side length is 11 ft

Answers

Answer:

1) -15/32

2) 2/15

3) -203.5

4) -3/2 = -1.5

5) 10/3 = 3 1/3

Step-by-step explanation:

For 1, you just multiply the numerators and denominators together (3 by 5, 4 by 8) and then because it is negative, add the negative sign.

For 2, you multiply again, but because there are 2 negative signs, it becomes positive.

For 3, you divide 81.4 by 0.4, you could also divide 814 by 4.

For 4, you keep change flip, so the equation would become -9/4 (-2 1/4=-9/4) and 3/2 would become 2/3. The equation would be (-9/4 * 2/3). Then, you would get -18/12 which is -3/2.

For 5, you just multiply 4/3 by 5/2 which is 20/6 and because 2 negatives, it becomes positive.

1. -15/32

-3/4 TIMES 5/8. So what you are going to do is multiply the bottom number by the top number and remember that a negative times positive equals negative. -3 times 5 equals -15 so that's the top number. Then, do the bottom number and it's 8 times 4, which is 32.

2. 2/15

So you do the same stuff for the last problem but now for this one so -1 times -2 is positive 2 so that's going to be the top number. Then 5 times 3 is 15.

3. -203.5

(-81.4)/0.4. So what you can do is do long division and get -203.5.

4. -1/5

(-2 1/4)/11/2. So what we can do is put the first fraction into improper fractions. So that would be -9/4 DIVIDED by 11/2. So then you're going to multiply 11/2 by 2 and get 22/4. Now we have -9/4 divided by 22/4.

5. 3 1/3

Switch them to improper fractions. -4/3 times -5/2. This will definitely be a positive because of the fact that it's a negative times a negative. This would equal 20/6 which can be simplified to 3 and 1/3.
