Answer 2

Answer:

Angle is of 45°

Step-by-step explanation:

Step 1 : Define x

Let the angle be x°

∴ Supplementary angle = 180 - x

∴ Complementary angle = 90 - x

Step 2 : Find for x

According to the question,

(180 - x) = 3(90 - x)

→ 180 - x = 270 - 3x

→ -x + 3x = 270 - 180

→ 2x = 90

∴ x = 45

Step 3 : Find the angle

∴ The required angle → x

→ 45°

∴ The required angle is of 45°
