Question

Solve for value of y.

Answer 1

Answer:

y = 6

General Formulas and Concepts:

A box at an angle signifies a 90° angle.

• The 2 angles that add up to 90° are called Complementary Angles

Step-by-step explanation:

Step 1: Set up equation

The 2 angles are Complementary Angles. They must add up to 90°.

(6y + 5) + (8y + 1) = 90

Step 2: Solve for y

1. Combine like terms:                         14y + 6 = 90
2. Subtract 6 on both sides:                 14y = 84
3. Divide both sides by 14:                    y = 6

Answer 2

Answer:

y = 6

Step-by-step explanation:

So, the two angles sum up to 90 degrees.

Based on that, form an equation;

6y + 5 + 8y + 1 = 90

simplify,

6y + 5 + 8y + 1 = 90

14y + 6 = 90

inverse operations,

14y + 6 = 90

      -6     -6

14y = 84

/14     /14

y = 6
