Let the angles of the triangle be 2x°, 3x° and 5x°.
As we know that the sum of all angles of a triangle is 180°,
therefore,
2x+3x+5x = 180
or, 10x = 180
or, x = 180/10
or, x = 18
- 2x° = (2×18)° = 36°
- 3x° = (3×18)° = 54°
- 5x° = (5×18)° = 90°
Hence, the measure of the angles are 36°, 54° and 90° respectively.
Hope this helps you to get to your answer.

Step-by-step explanation:
let all angles will be2x,3x,5x
2x+3x+5x=180deg(angle sum property)
10x=180deg
x=180/10deg
x=18 deg
so,1)2x=2×18=36deg
2)3x=3×18=54deg
3)5x=5×18=90deg
this is your answer please mark this as brainliest answer
