Answer:
Congruent
Step-by-step explanation:
by definition, the base angles of an isosceles triangle are the same value.
i.e they are congruent.
A' = (-2, 1)
B' = (1, 0)
C' = (-1, 0)
80 + 5 is 85 in extended form
First we need to calculate the volume which is Base*depth or length*width*depth
first we have to change all the units so they are the same, 3 inches in this case will equal 1/4feet
multiply all the numbers together
35ft*12ft*1/4foot= 105 cubic feet
however the problem says the cost per cubic *yards*
so take the 105 cubic feet and divide by 3 (3 feet to a yard)
105/3 = 35 cubic yards
the cost of 35 cubic yards of concrete =
35*125= $4375
