We have y=2x and y=x+2
They both equal y, so substitute the first equation for y in the second equation.
2x=x+2
Let’s get x to one side. Let’s subtract x from both sides.
X=2
Since x=2, just plug in 2 for x.
2+2=4
So,
X=2
Y=4
Step-by-step explanation:
Because this is a right triangle and it is given that one angle is 45 than also the ather angle is 45 so this triangle has 2 equal sides.So also the ather side is 6 .
Hypotenuse can be found by pythagorean theorem
6^2+6^2=x^2
36+36=x^2
x=√72
D. If you are working hard, then you will get good grades.
