Type the correct answer in each box. if necessary, use / for the fraction bar(s). given: . if the coordinates of point a are (8 , 0) and the coordinates of point b are (3 , 7), the y-intercept of is . if the coordinates of point d are (5 , 5), the equation of line is y = x + .

4x and 6y

im not sure though

the answer is 489

step-by-step explanation:

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.

you divide them and then you get the answer i took this class this year
