A building that is 100 for tall casts a shadow that makes a 30 degree angle. Approximately how long in feet is the shadow across

skad [1K]

Answer: 173.20 ft

Step-by-step explanation:

Observe the attached image. To know how long the shadow is, we must find the length of the adjacent side in the triangle shown. Where the opposite side represents the height of the building

By definition, the function $tan (x)$ is defined as

$tan(x) = \frac{opposite}{adjacent}$

$opposite = 100\ feet\\x=30\°$

$adjacent = l$

Then

$tan(30\°) = \frac{100}{l}$

$l = \frac{100}{tan(30\°)}$

$l = 173.20\ ft$

Gilda walks to the train station. If she walks at the rate of 3 mph, she misses her train by 7 minutes. However, if she walks at

lorasvet [3.4K]

We'll represent the distance as d and the time as t.
d= 3(t+7) because Gilda is 7 minutes late when travelling 3 mph
d= 4(t-5) because Gilda is 5 minutes early at 4 mph

d= 3t + 21
d= 4t -20
3t +21 =4t -20
41=t
d= 3(41) +21= 144
The distance is 144 miles.

A truck driver needs to drive 400 miles. The drivers average speed for the first 180 miles is b miles per hour. The drivers aver

nordsb [41]

Step-by-step explanation:

speed = distance/time

time = t = distance/speed

t = 180/b + (400-180)/c = 180/b + 220/c = 20(9/b + 11/c)
