Question

In three times the supp. of an angle is subtracted from seven times the comp. of the angle, the answer is the same as that obtained by trisecting a right angle. find the supplement pleasee help :)) The answer is 165 degrees i just need to show my work

Answer 1

let the angle be 'x'
let the sup of angle be 'x - 180'/'180 - x'
hence compliment of sup will be ( x - 90 ) or (90 - x)
trisecting the right angle mean each angle is 30 degree

hence as per the question,
3(x - 180) - 7(x - 90) = 30
3x - 540 - 7x + 630 = 30
4x = 60
x = 15 degree
that is the angle is 15 degree
you need the sup,
hence
180 - x is the sup
that is 165

Thanks :))
