Question

HELPPPPPPP MEEEEEEEEEEEEEEEEEEE

angles A and B are complementary angles. if the measure of Angle A= (7x+25), and the measure of Angle B is (x+9), then find the measure of Angle A

Answer 1

X = 6.5

To find the measure of an angle line the protractor and read what the number says

Answer 2

74 degrees

Explanation:

We first need to know what complementary angles are. Complementary angles are 2 angles that the sum is 90 degrees. We can write an equation:

(7x+25)+(x+9)=90

combine like terms

8x+34=90

subtract 34 from both sides

8x=56

divide both sides by 8

x=7

The next step, now that we have x=7, we need to find the measure of Angle A.

7x+25

substitute

7(7)+25

=74

So, Angle A is 74 degrees.

Hope this helps! :)
