Question

please tell answer for this question

Answer 1

let,
angle BOC=x
angle BAC=y

∴
2x=3y                           -1st equation              (given)

x=3y/2

x+y=180                       -2nd equation           (angles are supplementary)

substituting the value of x,

3y/2 + y =180
3y+2y=360
5y=360
y=360/5
y=72°

x=180-72
x=108°


ans:
x=108°
y=72°


hope it helps!!!
