Answer:
C) 5x-70=105
Step-by-step explanation:
As marked in the graph, angle 105 and angle (5x-70) equal to each other because they are vertically opposite angles therefore we have equation C)
Answer:
M= (1, 3)
Step-by-step explanation:
we have from the picture:
A = (-3,5)
C = (5, 1)
M = Midpoint
M =((x1+x2)/2), ((y1+y2)/2)
so we have:
x1= -3 y1 = 5
x2= 5 y2= 1
M= ((-3+5)/2) , ((5+1)/2)
M = ((2/2) , (6/2))
M= (1, 3)
Answer:
Step-by-step explanation:
![S_{31} = 9 \cdot 31 + [-0.5 \cdot \frac{31(31-1)}{2}] = 46.5](https://tex.z-dn.net/?f=S_%7B31%7D%20%3D%209%20%5Ccdot%2031%20%2B%20%5B-0.5%20%5Ccdot%20%5Cfrac%7B31%2831-1%29%7D%7B2%7D%5D%20%3D%2046.5)
