The isometric transformation transform the an image to another exactly with the same shape & same size:
The most known isometric transformation are:
Translation (slide the image)
Reflection (flip the image around an axis
Rotation (turn the image)
If you have to unknown variables, you have to eliminate one, e.g. Like this:
2×(2y-10)+3y=1240. Now there is only one unknown variable
4y-20+3y=1240
7y-20=1240
7y=1260
y=1260/7=180
Now you can calculate x
x=2y-10=2×180-10=360-10=350. ( You can also use the other equation but This one is easier)
Answer:7 cm
Step-by-step explanation: you know everything except the radius. Use this equation to help you: 44=2*pi*radius
Divide 44 by 2pi. Then u have your radius which is 7
