Where is the graph ??
Please provide the graph so that we can answer your questions ....
Answer:
y = 4
Step-by-step explanation:
Make equal ratios. y 10 4
=
x 22.5 9
If you divide 10 and 22.5, you get 0.44 repeating. If you divide 4 and 9, you will also get 0.44 repeating.
I think the answer shouls be 80. But its not given in the options.
Just saying this but don't go to that store! The answer, by the way is $1494
We'll use the Law of Cosines
We'll call
side a = length 5
side b = length 8
side c = length 10
and their corresponding angles as A, B and C
"C" would be the largest angle
cos (C) = (a^2 + b^2 - c^2) / 2 * a * b
cos (C) = (5^2 + 8^2 - 10^2) / 2 * 5 * 8
cos (C) = 25 + 64 -100 / 80
cos (C) = -11 / 80
cos (C) =

The largest angle is 97.903 Degrees
