Question

Angles a and b form a linear pair.

The ratio of a:b is 3:2. Find a and b.​

Answer 1

Answer:

A = 108°

B = 72°

Step-by-step explanation:

Let the angles be 3x, 2x

3x + 2x = 180°   (Linear Pair)

5x = 180°

x = 36

∴ A = 3×36 = 108°

  B = 2×36 = 72°

Answer 2

Answer:

A = 108° B = 72°

Step-by-step explanation:

let a be 3x and b be 2x

since A and B form a linear pair

so , 3x + 2 x= 180°

5x = 180°

X = 180° /5= 36°

Now, A = 3× 36= 108°

B = 2× 36 = 72°
