✔️ Question:-

In a right triangle ,the two smaller angles are in the ratio 1:4 compute these angles?

✔️ Answer:-

In a right angled triangle

angle B = 90

Let angle A = X

and angle C = 4X

So , we know , sum of all angles of a triangle = 180

⇒ 90 +X +4X = 180

⇒90 + 5X = 180

⇒5X = 180 - 90

⇒5X = 90

⇒X = 90÷5

⇒X = 18

So , if X = 18

4X = 4×18 = 72

So the angles are 18 and 72.
