Question

In a right angled triangle , one acute angle is 30 degrees . Find the other acute angle.
​

Answer 1

Answer:

Let the other acute angle be x.

Right angle = 90°

Acute angle = 30°

Sum of angles of a triangle = 180°

90°+30°+x =180°

120° + x = 180°

x = 180° - 120°

x = 60°

Answer 2

Answer:

in an triangle ,

a+b+c=180(angle sum property)

as it is a right angled triangle

a=90°

b=30°(given)

c=?

a+b+c=180

90+30+c=180

120+c=180

c=180-120

c=60(ans)
