From the top of a building that is 200 feet tall, Meryl sees a car coming toward the building. She measures the angle of depression when she first saw the car at 20° and when she lost sight of the car the angle was 40°. How far did the car travel? Round to the nearest tenth. Answer choices:

The car moved 549.5 feet while Meryl was watching it.

The car moved 238.4 feet while Meryl was watching it.

The car moved 311.1 feet while Meryl was watching it.

The car moved 273.6 feet while Meryl was watching it.

-6 is the correct option from the above given options

1/3 + 1/5 = 8/15.

step-by-step explanation:

hope it

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
