Answer:
13 units
Step-by-step explanation:
So the length of those 2 points is 6+6 = 12.
The height would be 8-3 =5
Using pythagoras, you can find out the length of the line joining the 2 points so:

units
X intercept is when y = 0
3x -15(0) = 60
3x = 60
x = 20
y intercept is when x=0
3(0) -15y = 60
-15y = 60
y = -4
Answer is C
Step-by-step explanation:
54×36=1,944 1,944÷73=23.63
The average of the given base lengths is the length of the midsegment:
... (72 + 104)/2 = 176/2 = 88
