Question

what is the measure of each angle?. (4x - 10) and (2x - 20)
they are complementary angles

Answer 1

Answer:

x=20

Step-by-step explanation:

(4x-10) + (2x-20) = 90

6x -30 = 90 (opening the bracket)

6x=90 +30

6x= 120

x = 120/6

= 20

Answer 2

Answer:

4x-10+2x-20=90

6x-30=90

6x=120

x=20.

Therefore, angles are 70° and 20°.
