Answer:

The measurement of two right angles of a right angled triangle are 'y' and '2y'. So the measure those two angles

Step-by-step explanation:

Given, the angle's of the triangle are angle be y°, 2y° and 90°

By angle sum property of the triangle, we get

(y + 2y + 90)° = 180°

y = 30°

2y = 60°

The measure of the three angles are 30°, 60° and 90°.
