How to find angle of right angle triangle in gre?

Answer 1

$\huge\tt\purple{Answer:}$

If we have to find two angles of a Δ , we can easily do that as we know one of the angles of a right angle triangle is 90°.Thus, Others can be easily found.

Sample Question :-

Two angles of a right angle triangle are in ratio 2:3. Find all the angles.

Answer:-

One angle of a right angle Δ = 90°

Let second angle be = 2x

Third angle = 3x

=> Sum of all angles of a triangle is 180°

=> = 90°+2x+3x=180°

= 5x=180-90°

= 5x= 90°

= x = 90/5 = 18°

Angles =

-> 90°

-> 2x = 18 x 2 = 36°

-> 3x = 18 x 3 = 54°
