Question

Find an angle if it is 20degree less than its complement

Answer 1

Step-by-step explanation:

Sum of complememtary angles= 90°

x+y= 90°

x+20= 90°

x= 90-20

Therefore, x= 70°

Answer 2

Answer:

$required \: angle \: is \: 35 \: degrees$

$let \: the \: angle \: be \: \alpha \\ then \: \alpha = (90 - \alpha ) - 20 \\ \alpha = 70 - \alpha \\ 2 \alpha = 70 \\ \alpha = 35 \\ \\ \\ therefore \: required \: is \: 35\: degree$
