The answers are x = 6 and z = 83

z can be found through the fact that the straight line created by it and the 97 degree angle would add to 180 degrees. After subtracting 97 from the 180 total, the answer of 83 would be apparent.

As for the x, the opposite angles will equal each other. Therefore:

11x + 31 = 97 ----> Subtract 31 from both sides
11x = 66 ---> Divide both sides by 11
x = 6

Find the area of the parallelogram that has a base of 2 1/2 ft and a height of 1 1/4ft

Marina CMI [18]

Answer:

The area of the parallelogram is $3\frac{1}{8}ft^{2}$

Step-by-step explanation:

Remember that a mixed fractions are composed for a whole number, a numerator and a denominator. For example in the mixed fraction $2\frac{1}{3}$ : 2 is the whole number, 1 is the numerator and 3 is the denominator.

If you want to convert to a improper fraction you need to multiply the whole number by the denominator and add to the numerator. The result will be the numerator of the improper fraction. The denominator remains the same.

$2\frac{1}{3}=\frac{(2*3)+1}{3} =\frac{7}{3}$
