To get the area its L x W = A.

So first divide 54 by 9 and you get 6.

9 is your length and 6 is your with.

Perimeter = L + L + W + W or L x 2 + W x 2

9 + 9 = 18 + 6 + 6 = 30 is your answer, so E

I believe the answer is $48 because 6 * 2 is 12 and 12 * 2 is 24 and 24 * 2 is 48, thus 48$. Please feel free to check my work, though.

What is the measure of angle 3?
zheka24 [161]
Angles 6 and 8 add up to equal 180, so 2x - 5 + x + 5 = 180.  3x = 180 so x = 60.  Angle 3 is alternate interior to angle 6 which is 2(60) - 5 = 115, so angle 3 is also 115

What are the coordinates of the endpoints of the mid segment of triangle ABC that is parallel to line AB?
MrMuchimi

Answer:

(4.5,4)  and  (4.5,6.5)

Step-by-step explanation:

we have the coordinates

A(2,7),B(2,2),C(7,6)

we know that

The mid segment of triangle ABC that is parallel to line AB is located between the mid point AC and the mid point BC

The formula to calculate the midpoint between two points is equal to

(\frac{x1+x2}{2},\frac{y1+y2}{2})

step 1

Find the mid point AC

we have

A(2,7),C(7,6)

substitute in the formula

(\frac{2+7}{2},\frac{7+6}{2})

(4.5,6.5)

step 2

Find the mid point BC

we have

B(2,2),C(7,6)

substitute in the formula

(\frac{2+7}{2},\frac{2+6}{2})

(4.5,4)

therefore

The endpoints of the mid segment of triangle ABC that is parallel to line AB are (4.5,4)  and  (4.5,6.5)
