5/12 is the answer just do 15 and then add 15 + 21 to get 36 and then you reduce 15/36 and get 5/12
The answer is the fourth one
Answer:
161.91
Step-by-step explanation:
First find the side length or YT by using the pythagorean theorem.
c= 129.2^2 = 16692.64
b= 68^2=4624
c-b = 12068.64
The square root of 12068.64 is approximately 109.86.
Using that length use the pythagorean theorem again and so:
a = 109.86^2 = 12068.64
c = 57^2 = 3249
a-c = 8819.64
The square root of 8819.64 is approximately 93.91.
So, 68 + 93.91 = 161.91
Answer:
B
Step-by-step explanation:
each side is corresponded to the other so Q=U and P=S
