Serena works at a sports complex that is laid out on a grid and each unit represents one foot. Serena was setting up for a soccer game and set up the corner flags on the corners of the soccer field at (50, 75), (50, 400), (260, 400) and (260, 75). She had to line between each of the corner flags with paint to create the edges of the field. Each can of paint can line 150 feet and costs $2.50. If she can only buy whole cans of paint how much will it cost her to line the field?

your answer is b ^w^ hope i

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
