Answer:
a = 57.5
b= 57.5
c= 57.5
d = 57.5
Step-by-step explanation:
I KNOW IT LOOKS WEIRD , I WAS SURPRISED TOO BUT IT IS THE RIGHT ANSWER :
a straight line is 180 - you take 65 degrees from it, and divide by two to get a and b which is 57.5 for both
then a triangle must equal to 180, the two lines crossing mean the are equal
180 - 65 = 115 / 2 = 57.5
therefore it is right
