Measure your givens first in the picture and go from there.
The answer is 18... hope this helps :D
C=√a²+b. square both sides
c²=a²+b². subtract a² from both sides
c²-a² = b². take the square root of both sides
b=±√c²-a²
but since length can never be negative we consider only the positive root
b=√c²- a²
You simply cross multiply. The correct answer is B. I know this becase I had the same exact question in my Staar review packet.
