Question

an angle is 30 degree more than twice its supplement. Find the2 angles.

Answer 1

Answer:

let the required angle be x,

then, its supplement=180°-x

now, according to question,

we have;

=> x=2(180°-x)+30°

=> x=360°-2x+30°

=> x+2x=360°+30°

=> 3x=390°

=> x=390°/3

=> x=130°

thus the required angle is 130°

and its supplement is (180°-130°)

ie. 50°
