Question

A ladder leaning against a wall forms a triangle and exterior angles with the wall and the ground. What are the measures of the two exterior angles? (These are (1) the ladder to the ground and (2) the ladder to the side of the house.) Justify your answer.

Answer 1

11x° is interior angle of ladder to the ground
and 7X° is interior angle of ladder to the wall

exterior angle of a ladder to wall is 180-7x
and exterior angle of a ladder to ground is 180-11x
