Answer:
a=54
b=36
c=144
Step-by-step explanation:
a:b=3:2
let common multiple be x
a=3x
b=2x
on line XY,
a+b+90=180 (angles on same line)
3x+2x+90=180
5x=180-90
x=90/5
x=18
a=54 , b=36
on line MN,
b+c=180 (linear pair)
36+c=180
c=180-36
c=144

Answer:
a = 135°
b = 90°
c = 90°
Step-by-step explanation:
Let the ratio of a and b = 3x and 2x
a + b + 90° = 180°
3x + 2x + 90° = 180°
5x + 90° = 180°
5x = 180°- 90°
5x = 90°
x = 90/5
x = 45°
Therefore, a = 3x = 3×45 = 135°
b = 2x = 2×45 = 90°
Also, b+c = 180° ...... linear pair
90° + c = 180°
c = 180°-90°
c = 90°
