Question

8) In the given figure line p is parallel to line q ; line l is parallel to line m .Using the measures of given angle find the measure of angle a and angle b .
​

Answer 1

Answer: a = 100° ; b = 100°

Step-by-step explanation:

a + 80° = 180° ( Linear Pair on the Same Side of the Line )

a = 180° - 80°

a = 100°

a = b ( Alternate Angle )

b = 100°
