Recall your d = rt, distance = rate * time.

let's say the Eastbound train is going at a rate of "r" mph, since we know the Westbound train is going faster 12 miles more than that, then the Westbound train must be going "r+12".

we also know that after 4 hours, both of them were 760 miles apart, so

\bf \begin{array}{lccclll}
&\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\
&------&------&------\\
Westbound&760&r+12&4\\
Eastbound&760&r&4
\end{array}
\\\\\\
\begin{cases}
760=(r+12)(4)\implies 190=r+12\\
760=4r\implies 190=r
\end{cases}
\\\\\\
\textit{since we know that r = 190, then }\qquad \stackrel{Westbound}{190+12}

Answer:

? = 36 degrees

Step-by-step explanation:

To find this measure, we use the appropriate trigonometric ratio

from the question, the angle faces the length 26 which represents the opposite

the length 44 faces the angle 90, which is the hypotenuse

The trigonometric ratio that connects both is the sine

The sine of an angle is the ratio of the opposite to the hypotenuse

Thus;

sine ? = 26/44

? = arc sine (26/44)

? = 36

If the volume of the pyramid is 64 ft³; and the height is 16 ft, what is the base area measured in square feet?
Law Incorporation [45]
The volume of a pyramid would be the base area times the height.
 Given the height and volume we can find the base ares by dividing the volume by the height.

64 / 16 = 4

The base area is 4 square feet
