Given a∥b and m∠5=77° .

What is m∠2 ?

Enter your answer in the box.

Step-by-step explanation:

m<5 and m<4 are  supplementary angles => m<5 + m< 4 = 180

                                                                         m<4 = 180 -77 = 103

m<4 and m<2 are corresponding angles => m<4 = m<2 = 103

step-by-step explanation:

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
