Answer:
y+6 = -5/4 (x-8) (this is point slope form)
Step-by-step explanation:
y-y1 = m (x-x1)
y- (-6) = -5/4 (x-8)
y+6 = -5/4 (x-8)
Center is (-6,7) and radius is 9. A circle with a center at (h,k) and a radius of r has the equation (x-h)^2 + (y-k)^2=r^2 so h= -6 k= 7 r is 9 you just work back wards, what two numbers multiplied gives you 81? Well 9
Answer:
here
Step-by-step explanation:
it is basically a sector , use the area formula i.e.
[(theta)/360]*πr^2
Answer:thats a triangle
Step-by-step explanation:
Answer:
40°
Step-by-step explanation:
<CAB=70°
<ABC=70°
<ACB+ <CAB+ <ABC=180(sum of angles in a triangle)
<ACB +70+70=180
<ACB+140=180
<ACB=180-140
<ACB=40°
