In order for a ski slope to be rated as a beginner slope, the maximum rise for a 10 foot run is 3 ft. Write the maximum slope of a beginner slope. A: 10/3
B: 3/10
C: 1/3
D: 1/10

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.
