Answers
Step-by-step explanation:
b = 147° ( vertically opposite angle )
c + 147 ° = 180° ( supplementary angle )
c = 180° - 147°
c= 33°...
Answer:
Step-by-step explanation:
b = 147° {Vertically opposite angles are congruent}
Linear pair: A linear pair is a pair of adjacent angles whose non-common arms form a line ( opposite rays)
c + 147 = 180 {Linear pair}
c = 180 - 147

So, it is proven that the area of triangle ABC is [tex]\frac{1}{2} * a*b*SinC[/tex].
What is a triangle?A triangle is a 2D shape having three sides and the sum of all angles is 180°.
We have,
A ΔABC,
And,
AB = c
BC = a
CA = b
H = Altitude of the triangle,
Now,
Area of triangle [tex]=\frac{1}{2} * Base *Altitude[/tex]
i.e.
Area of triangle ABC [tex]=\frac{1}{2} * a*h[/tex] .....(i)
Now,
Using trigonometric ratios,
[tex]Sin C = \frac{Perpendicular}{Hypotenuse}[/tex]
i.e.
[tex]Sin C = \frac{h}{b}[/tex]
We get,
h = b * SinC
Now,
putting this value in equation (i),
We get,
Area of triangle ABC [tex]=\frac{1}{2} * a*b*SinC[/tex]
So,
It is proved that area of triangle ABC [tex]=\frac{1}{2} * a*b*SinC[/tex] ,
Hence, we can say that it is proven that the area of triangle ABC is [tex]\frac{1}{2} * a*b*SinC[/tex], using trigonometric ratios and the triangle's area formula.

What is the surface area of a sphere ?Let, r be the radius of the sphere.
Then the surface area of the sphere = [tex]4\pi r^{2}[/tex] sq. unit
How to find the radius of the toy ball?The structure of the toy ball is sphere.
Given, Surface area of the toy ball = 7543 square millimeter
Let, the radius be r millimeter
∴ [tex]4\pi r^{2}[/tex] = 7543
⇒ [tex]r^{2}[/tex] = [tex]\frac{7543}{4*3.14}[/tex] , where [tex]\pi[/tex] = 3.14
⇒ [tex]r^{2}[/tex] = [tex]\frac{7543}{12.56}[/tex]
⇒ [tex]r^{2}[/tex] = 600.56
⇒ r = [tex]\sqrt{600.56}[/tex]
⇒ r = 24.5 (approx)

 Can a probability more than one or 100% Explain.
Answers
Answer:
No. Only 1 to 100, logically.
Let's make a scenario to solve this.
So let's say I have an all yellow, 9 quarter spinner board and I spin. It will always land on yellow, so it has a 9/9 or 100% chance of landing on yellow.
Now we must create another scenario.
For instance, I have one bottle, its starting direction was North, and I spin it. It will have a 1/4 chance of landing on North, East, South, or West because it will land in a random direction. For the 4 diagonal directions southeast, southwest, northeast, northwest it will be the same because there are only 4 directions, therefore giving the probability a 1 in 4 chance of landing on either one. :)

The experimental probability is 1/20 that a piece of paper randomly drawn from the bowl will have the number 35 written on it.
What is the stem-and-leaf diagram?A stem-and-leaf diagram is a quantitative assessment of a collection of data in which the data values are divided into a "stem" (the first digit of the number) and a "leaf" (the remainder of the number) (the last digit of the number).
As per the given stem-and-leaf plot, the required solution would be as:
First, determine the total number of pieces of paper pulled from the bowl by totaling the entries in the stem-and-leaf plot.
The stem-and-leaf layout has 40 numbers, with two of them being 35.
As a result, two of the forty pieces of paper drawn had the number 35 scrawled on them.
So, the experimental probability of the piece of paper having 35 on it is :
2/40 = 1/20.

If 6 boxes are in 1 pack and 12 in 2, you can use a ratio, which is 1:6 meaning for every 1 pack are 6 boxes.
There are two ways you can get an answer
Multiplication:
For however many packs there are you multiply it by 6 boxes.
For 4 packs, you multiply it by 6 boxes. You would get 24 boxes.
For 6 packs, you multiply it by 6 boxes again getting 36 boxes.
