Question

Right triangle in the ratio 1:4.compute these angles

Answer 1

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
