Question

If two angles of a triangle are 90°and 60°.Then find the third angle.

Answer 1

dude,

let the third angle be x
sum of all the angles of a triangle is 180°

90°+60°+x=180
150°+x=180°
x=180°-150°
=30°

hence,the third angle is 30°,ans.

have a nice day

Answer 2

Answer:

The third angle is 30°.

Step-by-step explanation:

Given, the two angles of a triangle are 90°and 60°.

To find: the third angle.

By angle sum property of triangle, the sum of all interior angles in a triangle is 180°.

90°+60°+x=180°

     150°+x=180°

              x=30°

Hence, the third angle is 30°.
