Question

If line q parallel line r line p is a transversal and if a=50,find value of f and g

Answer 1

The values of f and g are 100° and 80° respectively.

Step-by-step explanation:

Since line q || line r and line p is their transversal, then <g = <a ( Alternate exterior angles ) = <g = 80° ...Since <g and <f are forming a linear pair, then..<f + <g = 180° ( Angles are in a linear pair are supplementary ) = <f = 180° - <g.. = <f = 180° - 80° = 100°...Hence the values of f and g are 100° and 80° respectively..Hope it helps..♡
