Answer:given below

Step-by-step explanation:

sqrt x^2 +81= x + 10

x^2 + 81 = (x+10)^2

x^2 + 81 = x^2 + 20x + 100

so answer is:

x^2 + 81 = x^2 +20x + 100

Y= -3x-9 and y=1/3 x -39

iren2701 [21]

(9,-36)
X=9 Y= -36
-3x-9=1/3x-39
Solve it
The answer is x=9
Y=-3x-9
Y= -3(add the 9 because 9 is equal x) -9
Y=-3(9)-9
Solve it
The answer is y=-36

∠A and \angle B∠B are complementary angles. If m\angle A=(8x-28)^{\circ}∠A=(8x−28) and measure of angle B=(8x+22) ∠B=(8x+22) ,th

Afina-wow [57]

Answer:

Step-by-step explanation:

Basically we want to find x and then plug that in for angle B. How do we find x? Well, we know the angles are complimentary, which means theya dd to 90, so let's start with that.

A + B = 90

8x - 28 + 8x + 22 = 90

16x -6 = 90

16x = 96

x = 6

So there we go. Now to find B
