Question

In the given figure, PA || BC || DT and AB || DC. Find the values of 'a' and 'b'​

Answer 1

Step-by-step explanation:

a = 50 degrees. ( alternate interior angles)

b = angle BCD ( alternate interior angles)

a + b = 180 degrees ( sum of interior angles = 180 )

50 + b = 180

b = 180 - 50

b = 130 degrees.

therefore,

a = 50 degrees.

b = 130 degrees.
