Answer 1

Answer:

56°

Step-by-step explanation:

hii!

to solve this, we need to know that the angles of a triangle all add up to 180 degrees.

we are going to make an x equation here.

2x+3x+40=180

5x+40=180

    -40  -40

5x=140

/5   /5

x=28

angle a is 2x, so the answer would be 28*2 which is 56°

hope this helped out :)

Triangle HIJ is dilated by a scale factor of 55 to form triangle H'I'J'. Side I'J' measures 7575. What is the measure of side IJ? (marking brainliest)

Answers

Answer:

If triangle HIJ is dilated about the center of the triangle to create triangle H'I'J', dilated line A'B' will be parallel to AB.Option (D) is correct.

Given:

The options are as follows,

(A). be perpendicular to AB.

(B). lie on the same line as AB.

(C). shift four units to the left.

(D). be parallel to AB.

Step-by-step explanation:

If we dilate triangle HIJ then the dilated triangle  is bigger than the triangle HIJ.

The triangle HIJ is similar to triangle  to each other.

So the line  is parallel to side AB.

What are the solutions to the quadratic equation 4(x + 2)2 = 36

A. x = −11 and x = 7
B. x = −7 and x = 11
C. x= −5 and x = 1
D. x = −1 and x = 5

Answers

Answer:

C

Step-by-step explanation:

Given

4(x + 2)² = 36 ( divide both sides by 4 )

(x + 2)² = 9 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt{9}[/tex] = ± 3 ( subtract 2 from both sides )

x = - 2 ± 3 , then

x = - 2 - 3 = - 5 and x = - 2 + 3 = 1

4(-11 + 2)2 = -72
4(7 + 2)2 = 72
4(-7 + 2)2 = -40
4(11 + 2)2 = 104
4(-5 + 2)2 = -24
4(1 + 2)2 = 24
4(-1 + 2)2 = 8
4(5 + 2)2 = 56
