Question

If fig, 1 || m angle1 and angle2 are in the ratio 5: 4. Find angle3 and angle4.
​

Answer 1

Step-by-step explanation:

Let the common ratio be x

then 5x:4x,

Now,

Angle 1 + Angle 2 = 180° (Linear Pair)

5x + 4x = 180

9x = 180

x = 180/9

x = 20°

Angle 1 = 5x = 5(20) = 100°

Angle 2 = 4x = 4(20) = 80°

then,

Angle 2 = Angle 3 = 80° (corresponding angles)

Angle 3 + Angle 4 = 180°

80° + Angle 4 = 180°

Angle 4 = 180° - 80°

Angle 4 = 100°
