This is khan and I have 10 more problem academy. Some help please?

Step-by-step explanation:

Let's first start by establishing that when it comes to a reflection, side lengths and angle measurements remain the same. With that being said, let's identify our angle measurements:

As mentioned earlier, angle measurements will remain the same, so we can go ahead and identify the values of &

The sum of the angles in a triangle will always be equal to 180°.

Add the two identified angles of the original figure.

Subtract the sum from 180:

Therefore:

_

Check your work by adding the three identified angle measurements to see if they measure to 180°:

The answer is correct!

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

can you put the picture up?
