I would help but I cannot read it.
I don't know how to answer the first part but i'll solve it.
5(3+7)-5
5(10)-5
5x10-5
50-5
45
I'm guessing the answer is B? I tried to isolate r and I got that result. Sorry if it's wrong!
Answer:
100 ft
Step-by-step explanation:
We need to find the diagonal ( or hypotenuse)
We can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
80^2 + 60^2 = c^2
6400+3600 = c^2
10000 = c^2
Taking the square root of each side
sqrt(10000) = sqrt(c^2)
100 = c
