Right trapezoid wxyz is shown. what is the measure of angle wxy?

C.

Step-by-step explanation:

We have been given an image of a right trapezoid and we are asked to find the measure of angle WXY.

We can see from our given trapezoid that angle XYZ and angle WZY measures 90 degrees.

Since we know that trapezoid is a quadrilateral and sum of all angles of a quadrilateral equals , so we can set an equation as:

Upon substituting the given measures of our trapezoid we will get,

Therefore, the measure of angle WXY is 107 degrees and option C is the correct choice.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
