For this case we have:
By trigonometric property we have:
Where:
Substituting:
Clearing x we have:
Thus, the equation is:
Answer:
The distance between city C and city D is 450 miles.
<u>Solution:</u>
Given, The distance between City A and City B is 250 miles.
A length of 2.3 feet represents this distance on a certain wall map.
City C and City D are 4.14 feet apart on this map.
We have to find what is the actual distance between City C and City D?
Now, distance between a and b is 250 miles ⇒ 2.3 feet on map
Then, distance between c and d be n miles ⇒ 4.14 feet on map.
Now, by chris cross method.
250 x 4.14 = 2.3 x n miles.
2.3n = 1035
n = 450
Hence, the distance between city C and city D is 450 miles.
Answer:
Its b.
Step-by-step explanation:
m < 3 = m < 4 (vertical angles)
m < 1 = m < 5 ( alternate angles)
Therefore the triangles are similar.
Answer: 144 cubic feet
Step-by-step explanation:
Volume = base times height.
Base = 20 square feet
Height = 7.2 feet
Volume = 20 square feet * 7.2 feet = 144 cubic feet
Answer:
3(pi)
Step-by-step explanation:
8.33 (repeating 33) is 8.333333...
3(pi) = 9.42477796...
17/2 = 8.5
sqrt(64) = 8
Answer: 3(pi)
