first you can find angle C: A - 50 ⇒ 75 - 50 = 25° should know if you add all the angles in the triangle together you will always get 180 ° so now you can find angle B: 180- ( 75 + 25 ) ⇒ 180- ( 100 ) = 80° so the measure of angle A is: 75° the measure of angle B is: 80° the measure of angle C is: 25° i hope this is helpful have a nice day
