Question

Find the measure of an angle , if eight times its complement is 20° less than three times its supplement​

Answer 1

Answer:

Step-by-step explanation:

hello mate,

let the angle = x

according to question

its complement = 90-x

its supplement = 108-x

8(90+x)+20 = 3(180-x)

720+8x = 540-3x

720-540 = -3x-8x

180 =-11x

x= 180/-11
