Answer:
>
Step-by-step explanation:
We have been given a chord and tangent to a circle. We have been minor arc measure that is equal to
.
Since we know that angle formed by a secant and tangent of circle is half of the measure of intercepted arc.

We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.
Now we will plug given values in our formula,

Therefore, the measure of d is 121 degrees.
Answer: 
Step-by-step explanation:
The surface area of a rectangle can be calculated with:

The surface area of a trapezoid can be calculated with:

Calculate the area of the base, wich is a rectangle:

There are two equal rectangles, therefore, multiply the area of any of them by 2:

Calculate the area of the other rectangle:

There are two equal trapezoids, therefore, multiply the area of any of them by 2:

Therefore, the surface area will be the sum of all the areas calculated:

Answer:
80 miles per an hour
Step-by-step explanation:
400 divided by 5 equals= 80 so 80miles = 1 hour
26280 hours are in 3 years.
