Find the perimeter of the triangle shown using the Associative proprety. 4 1/2 in 5 1/2in 6 in

1 answer:

3 0

So assumn that the measures given are the legnths of the sides
perimiter=side1+side2+side3
so
side1=4 and 1/2
side2=5 and 1/2
side3=6
subsitute
p=(4+1/2)+(5+1/2)+(6)
associative prpoerty says (a+b)+c=a+(b+c) (it deals with addiont with parenthasees)
p=4+1/2+5+1/2+6
p=4+5+1/2+1/2+6
p=9+1+6
p=10+6
p=16 inches

Given that ABCD is a parallelogram. Find the following

7nadin3 [17]

Answer:

m=8

m<A=83

m<D=97

Step-by-step explanation:

Angles that are opposite of each other in a parallelogram are equal. Knowing this, we can first conclude that angle A and angle C are equal. We can set up the following equation:

$9m+11=8m+19$

Subtract both sides by 11

$9m+11-11=8m+19-11\\9m=8m+8$

Subtract both sides by 8m

$9m-8m=8m+8-8m\\m=8$

To calculate angle A, plug the value of m into its expression.

In a parallelogram, angles that share a side are supplementary, meaning they add up to 180 degrees. Therefore, angle A and angle D are supplementary. Knowing this, we can set up the following equation:

$180=83+D$
