## McGraw-Hill Math Grade 4 Answer Key Chapter 13 Lesson 5 Subtracting Angle Measures

**Solve**

**Write an equation and find the answer.**

Question 1.

âˆ ABD measures 95Â°.

âˆ ABC measures 32Â°.

What is the measure of âˆ CBD?

Answer:

95Â° – 32Â° = 63Â° or 32Â° + x = 95Â°

Question 2.

âˆ EFH measures 151Â°.

âˆ EFG measures 77Â°.

What is the measure of âˆ GFH?

Answer:

74Â°

Explanation:

âˆ EFH measures 151Â°

âˆ EFG measures 77Â°

151 – 77 = x

Subtract 77 from 151

151 – 77 = 74

X = 74

So, âˆ GFH measures 74Â°.

Question 3.

A lock is set at 0. Its arrow is turned 117 degrees forward and 23 degrees backward Then it is turned forward 54 degrees. At what degree measure is the arrow pointing?

Answer:

148 degree

Explanation:

A lock is set at 0

Its arrow is turned 117 degrees forward and 23 degrees backward

Subtract: 117 – 23 = 94

Then it is turned forward 54 degrees

Add: 94 + 54 = 148

So, the arrow is pointing at 148 degrees.
