Question

An angle is 25° less than its complement. What is its measure?

Answer 1

Let an angle be x

Its complement = 90° – x

According to question

x = 90° – x – 25°

⇒ 2x = 65°

⇒ x = 32\(\frac { { 1 }^{ 0 } }{ 2 }\)

Hence, measurement of the required angle be 32\(\frac { { 1 }^{ 0 } }{ 2 }\).
