Answer:

q = 14

General Formulas and Concepts:

Order of Operations: BPEMDAS
Equality Properties
Complementary Angles: Angles that add up to 90°

Step-by-step explanation:

Step 1: Set up equation

The 2 angles must add up to 90°.

(4q - 5)° + 39° = 90°

Step 2: Solve for q

Combine like terms: 4q + 34 = 90
Subtract 34 on both sides: 4q = 56
Divide both sides by 4: q = 14
