Answer:

15° and 75°.

Step-by-step explanation:

The triangle is a right triangle, so

                                          5y + y + 90 = 180

Subtract 90 from each side:     5y + y = 90

Combine like terms:                       6y = 90

Divide each side by 6:                      y = 15

Multiply each side by 5                  5y = 75°

The angles are 15 ° and 75° .

Answer:   y = 15°,  5y = 75°

Step-by-step explanation:

The Triangle Sum Theorem states that the sum of the angles of a triangle is 180°.  Reminder that a right angle is 90°

y + 5y + 90 = 180

     6y         =   90

    ÷6             ÷6  

       y         =   15

Now, let's find the measure of the other angle:

5y = 5(15) = 75
