Can some one help me out!!

The measure, in degrees, of ∠ABC = 25°

Hence, option A is true.

Step-by-step explanation:

Given

The exterior angle m∠CBD = 155°

To determine

The measure of ∠ABC

We know that the exterior angle and interior angle are supplementary angles.

In other words, adding the interior angle and an exterior angle would give us 180°.

Here:

m∠CBD = 155° is exterior angle

∠ABC is the interior angle.

When we add m∠CBD and m∠ABC we would get 180°.

m∠CBD + ∠ABC = 180°

substituting m∠CBD = 155°

155° + ∠ABC = 180°

∠ABC = 180° - 155°

∠ABC = 25°

Therefore, the measure, in degrees, of ∠ABC = 25°

Hence, option A is true.
