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)

<u>Find the value of x</u>

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

solve for x

25=-3x-8

3x=-8-25

x=-33/3=-11

<u>Find the value of m</u>

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

solve for m

m=180\°-10\°=170\°

Part 2)

<u>Find the value of x</u>

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

<u>Find the value of m</u>

(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 value of y varies directly with x. If x = 5 when y = 12, what is the value of x whon y = 30?
Brrunno [24]

Step-by-step explanation:

y = kx, where k is a real constant.

When y = 12, x = 5.

=> (12) = (5)k, k = 2.4.

Therefore when y = 30,

x = y/k = (30)/(2.4) = 12.5.

The answer is 12.5.
