You only showed B but it’s not B
Step-by-step explanation:
9 + y^2 = 49
y^2 = 40
y = √40 = 2√10
4.5/3 = 2√10/5x
22.5x = (3) 2√10
22.5x = 6√10
x = 6√10/22.5 = 3√10/11.5
Answer: x=84
Step-by-step explanation: Solve for x by simplifying both sides of the equation, then isolating the variable.
I hope this helps you out. :)
