Answer 1

The measure of angle B is 55 degrees.

What is the measure of angle B?

We know that the sum of the interior angles of any triangle must be 180°.

Here we have a right triangle, so we have a 90° angle at C.

Then we can write the equation:

35° + 90° + B = 180°

Solving this equation for B we will get:

B = 180° - 90° - 35°

B = 55°
