In triangle ABC there is AD bisector, angle C = 90, angle CAD = 24. find corner B.

Let’s calculate what the degree value of the angle A will equal, if we know, based on the conditions of this task, that the segment AD is the bisector of the angle A, while the degree value of the angle CAD is 24 °:

2 * 24 = 48.

Let’s calculate what the degree value of the angle B will equal, if we know, based on the conditions of this task, that this triangle is rectangular:

180 – 90 – 48 = 42.

Answer: The degree value of the angle B of the indicated triangle ABC is 42 °.
