Question

An angles is30 degree less than two times its supplement. find the angles?

Answer 1

Answer:

the angles are 52.5 and 37.5 respectively.

Explanation:

x+y=90

$2x = y - 30$

$x = y - 15$

$(y - 15) + y = 90$

$2y = 105 \div 2$

$y = 52.5 \\ x = y - 15 \\ x = 52.5 - 15 \\ x = 37.5$

verification : 52.5 + 37.5 = 90
