Answer:
a=7 b=24 c=25
Step-by-step explanation:
Leg a=7
Leg b=24
According to Pythagorean theorem: a^2+b^2=c^2
49+576=c^2
C^2=625
c=25
This is a right triangle, so we may apply the Pythagorean Theorem. The two leg lengths are 7 and 24 respectively, and so the length of the hypotenuse is
√(7² + 24²) = 25
60
AOC= AOB+ BOC
104= 7x+30 +9x+42
104= 16x+72
subtract both sides by 72
104-72=16x
32=16x
divide both sides by 16
x=2
BOC= 9(2) +42
BOC= 60
The answer is B.
