Answer:
144º
Step-by-step explanation:
(n-2)180 = total º inside, then subtract all the angles u know u have from that number
Midpoint formula : m = (x1 + x2) / 2 , (y1 + y2) / 2
midpoint is (6,4)
one point is (2,1)...x1 = 2 and y1 = 1
(6,4) = (2 + x2) / 2 , (1 + y1)/2
so 2 + what divided by 2 = 6....
(2 + x) / 2 = 6
2 + x = 6 * 2
2 + x = 12
x = 12 - 2
x = 10
and 1 + what divided by 2 = 4..
(1 + y)/2 = 4
1 + y = 4 * 2
1 + y = 8
y = 8 - 1
y = 7
so ur other endpoint is : (10,7)
Hi there! To find the answer to that question, we can write and solve a proportion. Set it up like this: 240/x = 60/100. This is because we're looking for the whole and we already know the part, which is 240. Cross multiply the values in order to get 24,000 = 60x. Now, divide each side by 60 to isolate the variable. When you do, you get x = 400. You can check this by dividing and then multiplying that quotient by 100. 240/400 is 0.6 and 0.6 * 100 is 60. That makes 60%. There. 240 is 60% of 400.
