Answer:
45
Step-by-step explanation:
because its a right angled triangle which should be 90 degrees so 90-45=45 so AC is 45 and AB is 45 so the triangle ACB is 90
N - 18 = -6
n - 8 = -6
+ 18 + 18
n = 12
(-1,5) = (x1,y1)
(3,13) = (x2,y2)
slope(m) = (y2-y1)/(x2-x1)
= 2
by using slope point form
y-y1 = m (x-x1)
y-5 = 2(x+1)
2x-y+7=0
