Question

Find the following angles​

Answer 1

If AC is a diagonal, we know that it cuts angle C in half. And we know that triangles add up to 180 degrees, as do supplementary angles.

Angle C: 45 degrees

90 / 2 = 45

Angle E: 108 degrees

180 = 63 + 45 + x

x = 72

E = 180 - 72 = 108

Angle A: 90 degrees

This is a square, and since AC is a diagonal, which cuts the angle in half, A must be 90 degrees.

Angle B: 117 degrees

180 - 63 = B

B = 117

Hope this helps!! :)

Answer 2

Answer:

Downwards ↓

Step-by-step explanation:

a°=90° (right angle)

c°=45° (diagonal)

b°=180-63 (angles on a straight line)

=117°
