Answer:

E, 297.1

Step-by-step explanation:

First, find the area of the triangle using the formula a= (bh) / 2

Base x height would be 16 x 12, which is 192

192 / 2 is 96 sq meters

Then, find the area of the circle using the formula a= Pi (r^2)

If the diameter is 16, the radius would be 8 because you divide by 2

8^2 is 64, 64 times Pi is approximately 201.1

Finally, add the areas together, 96 + 201.1 is 297.1 or E

Figure WXYZ is a parallelogram.

sergiy2304 [10]

see the attached figure to better understand the problem

we know that

In a parallelogram opposite angles are congruent, and consecutive angles are supplementary

in this problem

∠Y= $125$ °

∠W=∠Y

∠W= $125$ °

∠Z=∠X

∠Y+∠Z= $180$ °

∠Z= $180-125$

∠Z= $55$ °

∠X=∠Z

∠X= $55$ °

therefore

the answer is

∠Y= $125$ °

∠W= $125$ °

∠X= $55$ °

∠Z= $55$ °

PAINTING Lisa is painting a fence that is 26 feet long and 7 feet tall. A gallon of paint will cover 350 square feet. Write and

skelet666 [1.2K]

First we need to find the area of the fence, since paint covers square feet and squared units refers to area. The area of the fence is 26 x 7, which is 182 sq ft. If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom. $\frac{1}{350} = \frac{x}{182}$ . Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.
