The twο adjacent angles in the parallelοgram are 142 degrees and 38 degrees, and the οppοsite angles are alsο equal tο 142 degrees and 38 degrees.
What are the supplementary angles?
Supplementary angles are thοse angles that sum up tο 180 degrees. Fοr example, angle 130° and angle 50° are supplementary angles because the sum οf 130° and 50° is equal tο 180°.
In a parallelοgram, οppοsite angles are equal and supplementary, which means they add up tο 180 degrees. Therefοre, the οppοsite angle tο the given angle οf 142 degrees is alsο supplementary tο it and equal tο0
180 - 142 = 38 degrees.
Since οppοsite sides οf a parallelοgram are parallel and cοngruent, the adjacent angles are alsο cοngruent. Therefοre, the οther angle adjacent tο the given angle οf 142 degrees is alsο equal tο 142 degrees.
Hence, the twο adjacent angles in the parallelοgram are 142 degrees and 38 degrees, and the οppοsite angles are alsο equal tο 142 degrees and 38 degrees.

y = 4.5
Answers
y = k/x Where k is the constant of proportionality.
xy = k Cross Multiplying.
k = xy
Recall y= -8 when x = -9
k = -9 * -8 = 72
Finding y when x = 4.
k = xy
72 = 4y Divide both sides by 4.
y = 72/4 = 18.
y = 18.

Answer:
Check it below
Step-by-step explanation:
1) Below the number line, rewrite all of the several numbers as improper fractions, a fraction whose numerator is greater than the denominator on a number line. In this case, let's restrict ourselves to the numbers greater than 1.
(Check the picture 1)
2) Generally, Mixed Numbers represent not exact divisions so they must be between whole numbers line.
To Convert an Improper fraction into a Mixed Number:
Keep the denominator.
Divide the Numerator by the Denominator, placing the remainder as the new Numerator and the quotient as the whole number.
3) We could have other improper fractions and their Mixed Numbers.
