Question

In right triangle ABC,
M<A = 42º. Find m<B.​

Answer 1

The calculated measure of the angle B in the right triangle is 48 degrees

How to detemrine the measure of the angle B

From the question, we have the following parameters that can be used in our computation:

The right triangle

The sum of angles in a right triangle is 180

Using the above as a guide, we have the following:

B + 42 + 90 = 180

So, we have

B + 132= 180

Evaluate

B = 48

Hence, the measure of the angle B is 48 degrees

Answer 2

The answer for the above posted problem is 48°

Explanation:

Here we will apply angle sum property of triangle, i.e, the sum of three angles of the triangle is 180°.

Given:

ABC is right angle triangle.

Solution:

so ∠C = 90° ( from given figure)

∠A =42° (given)

∠A + ∠B + ∠C = 180°

or, 42° + ∠B + 90° = 180°

or, ∠B = 180° - (90° + 42°)

= 48°

so ∠B = 48°

Thus we can conclude that ∠B = 48°
