A lawyer drives from her home, located 15 miles east and 28 miles north of the town courthouse, to her office, located 6 miles w

natali 33 [55]

Answer:

Step-by-step explanation:

I know the answer is 26 miles but I cannot figure out how they came up with that answer using the distance formula.It looks like you need to find the shortest distance (as the crow flies) between the home and the office.

Use the Pythagorean Theorem.

6^2 + 10^2 = c^2

136 = c^2

11.67 = c

4^2 + 14^2 = c^2

212 = c^2

14.56 = c

11.67 + 14.56 = 26.2 = 26 miles

A tourist looks out from the observation deck of the Space Needle in Seattle. The deck is at a height of 520 ft. She sees her fr

WARRIOR [948]

Answer:

Last option 527.7 ft

Step-by-step explanation:

From the diagram attached we can see the angle of depression is 80.2 which is equal to ∠ACB (alternate angles)

Height of the deck AB = 520 ft. and we have to calculate the distance H between the tourist and her friend.

Sin ∠ACB = $\frac{AB}{AC}$

Now we apply sin rule sin 80.2 = $\frac{520}{H}$

$.9854=\frac{520}{H}$

$H = \frac{520}{.9854} = 570 ft$

So the tourist and her friend are 527.7 ft apart.
