Question

ABC and DEF intersect at point G. m GBH= 72 and m FEI= 35

Answer 1

m<ABH = 18°

m<DEI = 55°

AB, DE

Explanation:

In each of the two first cases, the sum of the measures oft he adjacent angles must be 90° for the lines to be perpendicular.

m<ABH = 18°

m<DEI = 55°

Theorem: If two lines are perpendicular to the same line, the lines are parallel.

AB, DE
