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
You have the ratio set up correctly:
2x+2/12 = x+3/21
Now cross multiply:
2x+2 * 12 = x+3 * 21
Simplify:
24x + 24 = 21x + 63
Subtract 24 from each side:
24x = 21x + 39
Subtract 21x from each side:
3x = 39
Divide both sides by 3:
x = 39/3
x = 13
