Answer:
Step-by-step explanation:
The universal set, U is a set of all vehicles produced by the manufacturer.
U = red, blue and green vehicles(both cars and trucks)
B = all red vehicles produced by the manufacturer(both cars and trucks)
C = red, blue and green trucks
C ' = all elements that are not in C but are in the universal set
C ' = red, blue and green cars
B intersection C ' = all elements that are common to set B and set C '. Therefore,
B intersection C ' = red cars
A trapezoid is a quadrilateral which means the sum of the angles should be equal to 360 degrees. The other angles therefore should have the sum of 360 - 60 - 45 = 255 degrees. Since we do not have the figure it would be hard to specify the measure of each angle.
If u use the app photomath it will give u answer with the steps too
