Answer:
18,72,90
Step-by-step explanation:
Let the measure of /_M be 'x'. As reported,
/_N is 5 times of x = 5x
/_O is 4 times of x = 4x
In any ∆, sum of interior angles is 180°.
=> /_M + /_O + /_N = 180
=> x + 4x + 5x = 180
=> 10x = 180
=> x = 180/10 = 18
Angles are x = 18°
4x = 4(18°) = 72°
5x = 5(18°) = 90°
