Looooking for x so the answer is
X=7
Answer:
(x + 7)2 + (y + 1)2 = r2.
To get we use point (8, 7): (8 + 7)2 + (7 + 1)2 = r2, r2 = 225 + 64 = 289 = 172.
So, equation of circle: (x + 7)2 + (y + 1)2 = 289
Step-by-step explanation:
Answer:
Step-by-step explanation:
Find the slope using the points, (1, -3) and (3, 1):
m = 2
Find the y-intercept (b) by substituting x = 1, y = -3, and m = 2 in
Subtract 2 from both sides
Plug in the value of m and b into the slope-intercept form equation, .
Thus:

Answer:
60 I think
Step-by-step explanation:
draw a straight line to make it a triangle then you know that angles in a triangle add up to 180.
so,
180-140=40
180-100=80
40+80=120
180-120=60
x=60
I think it's 60
