If the triangle is an equilateral triangle the angles should be all 60 as (60+60+60=180) if that’s true then a congruent line from the triangle would form a 60 degree angle.
so x=60°
Dude it keeps saying incorrect when i put the answer bro it says it again
In the question you provided above what do you mean can you please give more details.
1. you could distribute the 2 which would give you 2m - 16 + 3 = 17
2. You could add the 2 and 3 together and the problem would be 5(m - 8) = 17
For this case we have the following transformation:

Using the transformation we have that the image is:

Therefore, making use of this information, we can find the coordinates of the pre-image
We have then:

From here, we clear x:

On the other hand we have:

From here, we clear y:

The coordinates of the pre-image is:
Answer:
A point that is the pre-image is:
