Answer:
36°, 54°, 90°
Step-by-step explanation:
The ratio of the angles is 2:3:5.
Let’s represent the angles by 2x, 3x, and 5x.
The sum of the interior angles of a triangle is 180°.
2x + 3x +5x = 180 Combine like terms.
10 x = 180 Divide each side by 10
x = 18°
The angle measures are 36°, 54°, and 90°
