Question

• The angles are supplementary and the larger is 20° less than three times
the smaller​

Answer 1

Answer:

let the larger angle be x and smaller be y

now x+y=180........eq 1

by the given condition

x=3y-20

i.e.x-3y=-20.......eq2

substracting eq from eq

we get

4y=200

y=200/4=50 ........eq3

using eq3 in eq 1

we get x=130

therefore the larger angel is 130 and smaller angle is 50
