if one angle of a triangle is 100 degrees and the other two angles are equal, what is the measure of each unknown angle

Respuesta :

Answer: 40 degrees

Step-by-step explanation:

The 3 angles of a triangle must add up to 180 degrees.

Let's say this is triangle ABC and angle A has a measure of 100 degrees.

That leaves 80 degrees to be split evenly between angles B and C.

80/2 = 40, so angles B and C must each be 40 degrees.
