Answer:

1. 90°. 2 angles that to be 90° are complementary.

2. Angle A & Angle D add up to make a straight line, which is 180°. Those are called supplementary angles.

3. Angle E & Angle H add up to 90°. If H is 43°, then E is 47°.

G & H add to 180°. If H is 43°, then G is 137°.

E & F add to 180. If E is 47°, then F is 133°.

4. If G is 132°, and G & H add to 180°, then H is 48°.

If H is 48°, and E & H add to 90°, then E is 42°.

If E is 42°, and E & F add up to 180°, then F is 138°.

Explanation:

The square on an angle means it is a right angle. Right angles are 90°.

Supplementary angles make a straight line and add up to 180°
