Question

One of the acute angles of a right triangle is 50°. Find the other acute angle.

Answer 1

In a right angle triangle, one of the angles is 90^o.
It is given that one of the acute angled of the right angled triangle is 50^o.
We know that the sum of the measures of all the angles of a triangle is 180^o.
Now, let the third angle be x.
​Therefore, we have:
90^o​ + 50^o + x = 180^o
⇒ 140^o + x = 180^o
​ ⇒ x = 180^o $-$ 140^o
⇒ x = 40^o
​ The third acute angle is 40^o​.
