For this case we can model the problem as a rectangle triangle.
We know:
Angle between the base of the triangle and the hypotenuse
Length of the base of the triangle
We want to know:
Length of the hypotenuse.
For this we use the following trigonometric relationship:
Clearing h we have:
Answer:
the ladder is 30.9 feet long:
d) 30.9 ft
There is a formula for this:
Total Time = (worker1 * worker2) / (worker1 + worker2)
(3 * 8) / (3 + 8)
24 / 11 =
2.1818181818 hours
65 miles per hour meaning 65 miles in 60 minutes
65/60 = 1.083mile per minute
125/ 1.083 = 115.4 minutes to drive from san diego to malibu
check
115.4 x 1.083 = 124.97 (round up)
= 125
therefore it takes 115.4 minutes to drive from San Diego to Malibu
