<u>x = 8</u>
<u>y = 3</u>
x = 5y - 7
x + y + 1 = 12
Because we have a value for x, we can use it in the second equation to find the value of y.
5y - 7 + y + 1 = 12
<em><u>Combine like terms</u></em>
6y - 6 = 12
<em><u>Add 6 to both sides.</u></em>
6y = 18
<em><u>Divide both sides by 6.</u></em>
y = 3
Now that we have a value for y we can place it back in the equation to find the value of x.
x + 3 + 1 = 12
<em><u>Subtract 4 from both sides.</u></em>
x = 8
(X+2)^2-4 = (X+2)(x+2)-4
Factor:
X^2+4x+4-4
X^2+4x
X(x+4)
X=0, x=-4
The triangle has a translation. All corresponding angles remain congruent. Every point changed coordinates. The triangle retains the original size.

To find the last angle, add the 90 degree angle and 65 degree angle.(155)
Since a triangle has a total of 180 degrees, subtract 155 from 180 to get the third angle.(25 degrees)
To find the last side, use the pythagorean theorem(a^2 + b^2 = c^2)
a^2 + 77^2 = 85^2
solve, and you'll get the last side
