Answer:
it’s 90 because there equal add both up to 180
You should use a calculator this is very easy, you just add up the things in common and then then divide
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
So it'll be...
y- -2
x- +5
U=units
A=πr²
=π(44)²
=6082.12u²
6082.12/121= 50.27
A=πr²
50.27=πr²
r²=50.27/π
r=√16
r=4u
