Two spiders are climbing up a wall. The first one is at a height of 8 feet from the ground and climbs at a speed of 6
feet per minute. The second is at a height of
20
feet from the ground and climbs
3
feet every minute.

After what time, in minutes, will the spiders be at the same height on the wall?

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.

your answer is -9
