Two parallel lines are crossed by a transversal. what is the value of a? a = 43 a = 63 a = 117 a = 137 two parallel lines are crossed by a transversal. bwhat is the value of h? h = 60 h = 80 h = 100 h = 120two parallel lines are crossed by a transversal. cwhat is the value of b? b = 32 b = 52 b = 118 b = 128

Part a) What is the value of a?

we know that

m∠a= -------> by corresponding angles

therefore

the answer part a) is

m∠a=

Part b) What is the value of h?

we know that

m∠h+ ---> by consecutive interior angles (supplementary angles)

m∠h=

m∠h=

therefore

the answer part b) is

m∠h=

Part c) What is the value of b?

we know that

m∠b= -------> by alternate interior angles

therefore

the answer part c) is

m∠b=
