In triangle ABC AC = BC, AD– height, angle BAD is 43. Find the value of angle C.

Consider triangle ABC:
1) angle BAD = angle ABC = 43 degrees (angles at the base of an isosceles triangle are equal)
2) angle C = 180 – 43 – 43 = 94 degrees (the sum of the angles in the triangle is 180 degrees)
Answer: 94 degrees
