ANSWER:
Question No. 1 -
37°
Question No. 2 -
Angles A and E
STEP-BY-STEP EXPLANATION:
Question No. 1 -
Angle sum of a triangle = 180°
THEREFORE:
Let unknown third angle in each triangle = x
x + 90 + 53 = 180
x = 180 - 90 - 53
x = 37°
Question No. 2 -
Angles A and E are alternate angles on parallel lines. Alternate angles on parallel lines are congruent. Therefore, Angles A and E are congruent.
60/80 = 3/4, x/32=3/4, (cross multiply) 4x= 96, x= 24

First, let's make the mixed fraction improper:
- (3 3/8)
- { [(8 · 3) + 3]/8}
- { [24 + 3]/8}
- {27/8}
- (3 3/8) - (7/8)
- (27/8) - (7/8)
as the denominators are equal, we operate only with the numerators
- 34/8 <em>simplifying</em>
<h2>- 17/4</h2>
