Determine the values of the variables in the parallelograms below help me please

PolarNik [594]

Answer:

Part 1)

$x=-11$

$m=170\°$

Part 2)

$x=-5, x=1$

$m=-10, m=14$

Step-by-step explanation:

we know that

In a parallelogram opposite sides and opposite angles are congruent, and consecutive angles are supplementary

Part 1)

Find the value of x

$25=-3x-8$ ----> opposite sides are congruent

solve for x

$25=-3x-8$

$3x=-8-25$

$x=-33/3=-11$

Find the value of m

$(70+(m-60))=180\°$ ----> consecutive angles are supplementary

solve for m

$m=180\°-10\°=170\°$

Part 2)

Find the value of x

$5=x^{2}+4x$ ---> opposite sides are congruent

using a graphing tool

see the attached figure N 1

The solutions are

$x=-5, x=1$

Find the value of m

$(m^{2}-4m)=140\°$ ---> opposite sides are congruent

solve for m

using a graphing tool

see the attached figure N 2

The solutions are

$m=-10, m=14$

The sum of two numbers is 65 one is 4 times as large as the others.what are the numbers?

bixtya [17]

let the numbers be n and m

n+m=65

n=4m

So when we put our work in:

4m+m=65

5m=65

m=13

n=52

So therefore your two numbers are 52 and 13!

Hope this helped! °ω°
