Question

the ratio of angles of a triangle I'd 2.3.5 the angles of a triangle are
a)72.100.18​

Answer 1

Step-by-step explanation:

Let the angles be 2x, 3x and 5x

Sum of angles in triangle = 180°

2x + 3x + 5x = 180°

10x = 180°

x = 180°÷10

x = 18°

2x = 2×18° = 36°

3x= 3×18° = 54°

5x= 5×18° = 90°
