You just answerd it yourself i think.......
Answer:
Step-by-step explanation:
27π=120°/360°*πr^2
81π=Area of circle
Answer:
m+n=140
Step-by-step explanation:
So the angles in a triangle always add up to 180. We already know that the first angle in the triangle is 40 degrees because it's shown in the angle below the triangle. So we have 140 degrees left since 40 is taken up. That eans m+n=140
j=2
Step-by-step explanation:
take the second numbers in each parentheses and subtract them. put this answer on top of a fraction
(j,3) (8,2)
2-3 = -1
take the first numbers and subtract. put this answer at the bottom of fraction
8 - J = 6
j = 2
answer should equal -1/6
the formula for a slope is y2-y1/x2-x1
look at the points like this, and fill in the places with the numbers and j they give you
(X1,y1) (X2,y2)
