Answer:
50 is answer
Explanation:
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°.
GIVEN :-
- one of the angle of a right angle triangle is 40°.
TO FIND :-
- The other angles of the triangle.
SOLUTION :-
In the question it is given that , the triangle is a right angle triangle , So in right angle triangle we have (say),
⇒ ∠1 = 40°.
⇒ ∠2 = 90°.
⇒ ∠3 = ?.
Now In right angle triangle by angle sum property we have,
⇒ ∠1 + ∠2 + ∠3 = 180°.
⇒ 40° + 90° + ∠3 = 180°.
⇒ 130° + ∠3 = 180°.
⇒ ∠3 = 180° - 130°
⇒ ∠3 = 50°.
Hence the other angles of the right angled triangle are 90° and 50°.
