Question

In the figure the lines AB and PQ are intersecting at 'O'.
angle ROB =90º, and a : b = 3 : 2 then find C' value.

​

Answer 1

Answer:

let the angles a and b be in the ratio 3x:2x

3x+2x+90=180( AB is a straight line)

5x=90

X=18

a=3x=3*18=54

angle a =angle C( vertically opposite angles)

angle C = 54
