A dolphin swims 665,280 feet in 3 hours. Use the formula d = it, where d represents distance, r represents rate, and t represents time,
Part A: Rearrange the distance formula, d = it, to solve for rate.
Part B: Find the dolphin's rate in feet per hour.
Part C: Find the dolphin's rate in miles per hour.
Part D: Which unit, feet, or miles, makes more sense to use in this scenario, and why

Step-by-step explanation:

Bruh someone answer I need this to

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.
