Question

The image below shows 2 complementary angles.

Answer 1

Answer:

a)(x + 3) + (2x - 3) = 90

b)(x + 3) + (2x - 3) = 90

    -3                     -3

-------------------------------

x + (2x-3)         = 87

          +3           +3

------------------------------

x + 2x                = 90

Simpify: x + 2x = 3x

3x/3 = 3

90/3 = 30

x = 30º

c)(30 + 3) = 33º for angle A

  (2x30-3)= 57º for angle B

Step-by-step explanation:

Set them equal to 90º because complementary means 2 angles that = 90º
