What is the measure of angle B in degrees?

Answer:
119°
Step-by-step explanation:
Angle C and the outside angle are supplementary meaning they equal 180°. 180-112=68, therefore angle C is 58°. All angles of a triangle are equal to 180°. 51+68=119, 180-119=61 therefore angle A is 61°. Angle A and B are also supplementary angles, 180-61=119, so angle B is 119°.
