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

On your calculator, use the normalcdf() function, enter the Lower Limit, Upper Limit, Mean, and Standard deviation.

The mean and standard deviation are given to you. You want to find "less than 13.5 seconds", meaning that 13.5 is the maximum "Upper Limit" and 0 would be the Lower Limit because we can pretend 0 second is the minimum. Don't worry about negatives, in this scenario, values like "-5 seconds" are impossible.

Enter normalcdf(0, 13.5, 13.56, 2.24) in a calculator and the output result is the answer.
