Dallas is putting down hardwood floors in his home. his
living room is pentagonal. each unit on the coordinate
plane represents 5 feet. find the area of flooring needed
in square feet.
which of the following is the total area of the living room

The total area of the living room is

Step-by-step explanation:

we know that

The total area of the living room on the coordinate plane is equal to the area of a triangle EHO plus the area of rectangle EOUS

so

we have

---> base of triangle

---> height of triangle

---> length of rectangle

--->width of rectangle

substitute the values

Remember that

Each unit on the coordinate  plane represents 5 feet

so

therefore

The total area of the living room is

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

exactly you go it
