Answer:
Part a) consecutive interior angles
Part b)
Part c) m∠5=
Explanation:
see the attached figure to better understand the problem
we know that
Part a) Angles 3 and 5 are consecutive interior angles
therefore
m∠3+m∠5=
Part b) we have
m∠3=
m∠5=
substitute
Part c) solve for x
Find the value of m∠5
m∠5=
m∠5=
