Simple drawing shows that measure interior angle at B is 25 degrees.

Easily seen from a drawing are that measure of angle CBD is 25 degrees, and measure of angle CAD is 65 degrees (which was already given).

Heres the plot formula!

In triangle △ABC, ∠C is a right angle and CD is the altitude to AB. Find the angles-example-1
