Answer:
(x,y) = (-219/9, -818/9)
Step-by-step explanation:
Answer: A
Explanation do Pythagorean theorem and find the third side. Then do adjacent/hypotenuse.
Answer: 15
Step-by-step explanation: 8 times 3 equals 24 then you subtract 9 from 24 which gives you 15.
Well, to find the perimeter we have to add all of the side lengths, so let's do that:
2x+3 +2x+3 +2x
And we know that this equals 36 so let's solve for x
2x+3+2x+3+2x = 36
6x+6 = 36
6x = 30
x = 5
So we know know that x = 5.
Now all you have to do is plug in the values of x into the lengths
2(5) + 3
= 10+3
= 13 is the length of two of the sides.
2x
= 2(5)
= 10
And 10 is the length of the last side.
