B^2 = a^2 - c^2
b^2 = 9^2 - 5^2
b^2 = 56
b = 7.5
Answer:
I believe the correct answer is D
Answer:

Sorry but your question is not too explanatory but I sure hope this helps
Answer:
A=672 m²
Step-by-step explanation:
a²+b²=c² (to find h)
14²+b²=50²
196+b²=2,500
b²=2,304
√b²=√2,304
b=48
h=48
(base×height)÷2
(28×48)÷2
1,344÷2
A=672 m²
it is a linear equation
if you take the negative of x and subtract 1 you get Y
so the answer is A
