Answer:
30°, 60°, and 90°
Explanation:
Since it is a right triangle, it has an angle of 90°. The angles of triangles always equal 180°, so that means there is 90° left. With that said, dividing 90 by 3 and adding two of the parts would show what is double of the other number. So, 90 ÷ 3 = 30; 30 × 2 = 60 | 60 is double 30, and 60 + 30 = 90. Hope this helps! Have a great day! :)
