Can someone help im struggling real hard

(8x - 9)˚ = 63˚

and

(3x)˚ = 27˚

Step-by-step explanation:

hee remember me?

Complementary angles are angles that equal 90˚, so we can create an equation:

(8x - 9) + 3x = 90

Remove the paranthesis

8x - 9 + 3x = 90

Add 9 to both sides

8x + 3x = 99

Simplify

11x = 99

divide both sides by 11

x = 9

So if we plug in x for 9 we get:

8x - 9

8(9) - 9

72 - 9

63

3x

3(9)

27

So

(8x - 9)˚ = 63˚

and

(3x)˚ = 27˚

30

i hope i

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
