In triangle ABC, angle A is 41 degrees, angle B is larger than angle C, and all three angles are prime numbers, in degrees. What is the measure of angle B?

We need to find two different primes that add to 180 - 41 = 139°

One prime must be even = 2°

The other must be = 137°

The angles can only be 2, 41, 137

So B = 137° and C = 2°
