Answer:
length of baseball bat.
Step-by-step explanation:
she can measure the bat and times by how many times she could fit the bat there u know
x=−7/8
√308 or 17.5
c^2=a^2+b^2
c^2-a^2=b^2
Substitute
18^2-4^2=b^2
324-16=b^2
b^2=308
b=√308 or b=17.5
to be entirely honest i do not know
remember: tan(theta) = opposite/adjacent
