In a right triangle, one angle is 90°. Then the measure of the angle ∠B will be 48°.
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
In right triangle, ∆ABC.
Angle ∠A = 42°.
Then the measure of the angle ∠B will be
We know that in a right triangle, one angle is 90°.
Then we have
∠A + ∠B + 90° = 180°
∠A + 42° + 90° = 180°
∠A = 48°
