Respuesta :

All angles in a triangle add up to 180°

So add the other two angles
90+35=125

Subtract the sum from 180
180-125=55

Angle b is 55°

The measure of angle B is 55°

The correct answer is an option (C)

What is right triangle?

"It is a triangle whose one of the angle measures 90° "

For given question,

We have been given a right triangle ABC.

Here, ∠A = 35° and ∠C = 90°

We need to find the measure of ∠B

We know that the sum of all angles of the triangle is 180°

⇒ ∠A + ∠B + ∠C = 180°

⇒ 35° + ∠B + 90° = 180°

⇒ ∠B = 180° - 125°

⇒ ∠B = 55°

Therefore,  the measure of angle B is 55°

The correct answer is an option (C)
