Question

a. Two complementary angles are x+20 and 2x-56 degrees. i. The value of x = ___ degrees. *​

Answer 1

Answer:

42

Step-by-step explanation:

complementary angles sum up to 90 degrees

x+20+2x-56=90

3x-36=90

3x=90+36

3x=126

x=126/3

x=42 degrees

Answer 2

Step-by-step explanation:

( x + 20 ) + ( 2x - 56 ) = 90

3x - 36 = 90

3x = 90 + 36

3x = 126

x = 126 ÷ 3 = 42

Therefore, the value of x = 42 degrees
