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!

m∠DBC =25°, m∠DCB =55°, m∠CDB =90°, m∠ACD =25°, m∠ADC =90°.

In triangle △ABC, ∠C is a right angle and CD is the altitude to AB.

We need to find the angles in △CBD and △CAD if m∠A = 65°.

What is the triangle?

A plane figure with three straight sides and three angles.

Consider △CAD

∠ADC =90°.

∠ACD+∠ADC+∠CAD=180°.

⇒∠ACD+90°+65°=180°

⇒∠ACD+90°+65°=180°

⇒∠ACD=180°-155°=25°

Consider △CBD

∠CDB =90°

∠DCB+∠ACD =90°

⇒∠DCB+25°=90°

∠DCB=55°

Now, ∠DBC+∠DCB+∠CDB =180°

⇒∠DBC+55°+90° =180°

∠DBC=25°

Therefore, m∠DBC =25°, m∠DCB =55°, m∠CDB =90°, m∠ACD =25°, m∠ADC =90°.
