Answer:
15° and 75°.
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°
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
