Question

One angle of a right angled triangle is 35 degree . Find the other angle ​

Answer 1

Answer:

55 degree is the third angle of the triangle

Answer 2

The other angle is  55°

Explanation:

Given:

1. One angle of a right-angled triangle is 35°

To find:

The other Angle

Formula:

The sum of the angles of a triangle = 180°

∠A+∠B+∠C = 180°

Solution:

==> ∠A+∠B+∠C = 180°

==> ∠A = 35°

==> In a Right-angled Triangle

==> One angle is 90°

==> ∠B = 90°

==> Find the Third Angle

==> 35° +90°+∠C = 180°

==> 125° + ∠C = 180°

==> ∠C = 180°-125°

==> ∠C = 180°-125°

==> ∠C = 55°

==> The other angle is  55°

==> Sum of the angles = 180°

==> 35°+55°+90° = 180°

==> 90°+90° = 180°

==> 180° = 180°

==> Hence proved
