Answer:
ts of the triangle in terms of x? Give your awnsnewk
Step-by-step explanation:
When solving a problem like this you can start with either ys are yz. To make it simple, lets start with ys, you are going to divide s underneath at the y, then do it the other side as which Will turn the equation into y+yz=x/z.Then you're going to do the same thing with yz making the equation y+y=x/z+s. Then add the 2 y's, to get 2y=x/z+s, Then for the final step you are going to divide 2 on both sides making the answer
Answer:

1. There are three ways to solve this: elimination, substitution, graphing.
2. I chose elimination, so I had to get one negative variable and one positive variable of the same value (for example, 18 and -18)
-7x+2y=-8
-16x+9y=26
I chose to get 2y and 9y to equal -18y and 18y.
So, multiply the first equation by -9. Multiply the second by 2.
63x-18y=72
-32x+18y=52
the 18s cross each other out. So you're left with
63x=72
-32x=52. Add them.
31x=124, divide both sides by 31, and you'll get 4.
x=4
Plug your answer for x into one of the equations. Let's use the first one.
-7(4)+2y=-8
-28+2y=-8. add 28 to both sides.
2y=20, divide both sides by 2.
y=10.
This makes your answer (4,10)
A would be the answer.
Step-by-step:
Pythagorean theorem-
a^2+b^2=c^2
24^2+45^2=c^2
576+2025=c^2
2601=c^2
square 2601= square c^2
51=c
