Answer:79°
Step-by-step explanation:
You do 9/10. Which here it only fits once. So this is 1 1/10. The other one fits 3 times. So its 3 1/10.
If you want the subtraction also done its 1 4/10.
I think it’s (-1,-6) for the first one. And the second one might be (3,-3). I’m so sorry if these are wrong. I haven’t done this in a few years
Let A be Area, s sides
A= s²
(400)1/4 = area of the smaller square.
100=s²
10²=s²
s= 10, so the smaller side is 10 inches.
