Question

A) one of the angles of a right angle triangle is 40 degree, find the other angles of the triangle.
​

Answer 1

Step-by-step explanation:

The triangle is right angle, which means one angle of the triangle is 90°.

We have also given one more angle of the triangle i.e., 40°.

Let, consider the 3rd angel be = x

Angel sum property of a triangle is =180°

=> 90° + 40° + x = 180°

=> 130° + x = 180°

=> x = 180° - 130°

=> x = 50°

Therefore, the third angle of a right angle triangle is 50°.

According to given question,

The size of the other 2 angle is = 90° + 50°

=> 140°

Answer 2

Answer:

In this question we have given,

The triangle is right angle, which means one angle of the triangle is 90°.

We have also given one more angle of the triangle i.e., 40°.

Let, consider the 3rd angel be = x

Angel sum property of a triangle is =180°

=> 90° + 40° + x = 180°

=> 130° + x = 180°

=> x = 180° - 130°

=> x = 50°

Therefore, the third angle of a right angle triangle is 50°.

According to given question,

The size of the other 2 angle is = 90° + 50°

=> 140°
