The midsegment is half the length of the base. So the base = 2*4 = 8 in.
Since it is an isosceles triangle, the other two sides are equal in length.
Perimeter = sum of two equal sides + base = 20 in.
2x equal side + 8 = 20
equal side = 12/2 = 6
Each of the equal sides = 6"
The coordinates of the midpoint of CD with endpoint at C(-7,-2) and D(-3,-5) is E(-5, -3.5)
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let (x, y) represent the coordinate of the midpoint E. Point E is the midpoint of CD, hence:
x = [(-7) + (-3)] / 2 = -5
y = [(-2) + (-5)] / 2 = -3.5

Answer:
A. (125.6 in)
Step-by-step explanation:
R = d / 2 = 40 / 2 = 20 in
Circumference is:
S = 2*π*R=2*3.14*20=125.6 in
Let the number be x
2/3*x - 2 = 10
or, 2/3 * x =12
or x= 12*3/2
or, x = 18
