Answer:

We know that sum of angles of right angle triangle is 180°

One angle is given---40°

Another angle is given---90°

40°+90°+x=180

x=180130

x=50°

Answer:

The third angle of the triangle is 50°.

Step-by-step explanation:

Given :

The triangle is a = Right angled triangle

One angle = 40°

To find :

The third angle

Solution :

Let the third angle as be as x

As it is mentioned that the triangle is a right angled triangle, The other 2 angles are

  • 90°
  • 40°

Solving according to the Angle sum property of triangle that all angles in a triangle sum up and make 180°.

\boxed{\sf{90+40+x=180}}

 \sf{\implies} \:90 + 40 + x = 180 \\ \sf{\implies} \:130 + x = 180 \\ \sf{\implies} \:x = 180 - 130 \\ \sf{\implies} \:x = 50

The third angle = 50°

\therefore The third angle of the triangle is 50°.
