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.

the interior has a radius of 3 so 3*3*3.14=28.26

the whole thing has a radius of 5 so 5*5*3.14=78.5

then 78.5-28.26= give you a total of 50.24 as area of the outer circle
