Answer:
117
Step-by-step explanation:
So basically, how I figured it out is 20-15 is 1/4 of 20. So I had to find the 1/4 of 52 which is 13. But 15 is 3/4 of 20 so then you multiply 13 times 3 which is 39.
10 is half of 20. So you find half of 52. Which is 26.
52+39+26 is your equation.
Which adds up to 117. So 117 is your answer
I used 20 because in the smaller triangle 20 was the largest side like 52 in the biggest triangle.
