McGraw-Hill Math Grade 4 Answer Key Chapter 13 Lesson 5 Subtracting Angle Measures
Solve
Write an equation and find the answer.
Question 1.
∠ABD measures 95°.
∠ABC measures 32°.
What is the measure of ∠CBD?
Answer:
95° – 32° = 63° or 32° + x = 95°
Question 2.
∠EFH measures 151°.
∠EFG measures 77°.
What is the measure of ∠GFH?
Answer:
74°
Explanation:
∠EFH measures 151°
∠EFG measures 77°
151 – 77 = x
Subtract 77 from 151
151 – 77 = 74
X = 74
So, ∠GFH measures 74°.
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.
