Answer:
The answer here is C. 64 degrees
Step-by-step explanation:
This is a isosceles triangle and the base angle is given to you as 58 degrees. There are 2 base angles in a Isosceles triangle so you would add 58+58=106 and triangles angles always add up to 180 degrees so you would then do 180-106=64 which then gives you your answer C.64 degrees. Have a good day :)!
