Classify the pair of angles. Then find the value of x
For all 4 questions pls

4. x = 42°

5. x = 18°

6. x = 74°

7. Unknown.

Step-by-step explanation:

4. (x-5) = 38° ⇒ x = 38 + 5 ⇒ x = 43°

5. 2x + 3x = 90° ⇒ 5x = 90° ⇒ x = 18°

6. 2x + 32° = 180° ⇒ 2x = 180°- 32 ⇒ 2x = 148° ⇒ x = 74°

7. Not sure since the picture missing that angle off page.
