Ramps in a parking garage need to be steep. The maximum safe incline for a ramp is 8.5 degrees. Is this ramp safe? If not, provide dimensions that would make the ramp safe.

Step-by-step explanation:

According to the ADA recommendations, a 1:12 slope is a safe ram, or about 5 degrees of incline.

In this case, we have a ramp with 8.5 degrees, which is almost double than the number for safe ramps.

Therefore, the given ramp is not safe.

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.
