Answer:
Step-by-step explanation:
Let x represent the sun's angle of elevation.
We have been given that a 6-foot tall man casts a shadow that is 12 feet long.
Upon looking at our attachment we can see that man and his shadow forma a right triangle with respect to ground, where height of man is opposite side and his shadow is adjacent side.
Since tangent relates opposite side of a right triangle with adjacent, so we can set an equation as:
Using arctan we will get,
Therefore, the measure of the sun's angle of elevation is 27 degrees.
First find the circumference which should be 10*2 is 20 for diameter and then pi 3.14 to times it give u the circumference and then use for the arc length formula

A)
Let X be the food expenditure of a family.
Let the population mean of an expenditure of a family be.
Let the population standard deviation of an expenditure of a family be.
The proportion families spend more than $30 but less than $490 per month on food is,
159 seconds. The 1st two slices of bread will take 60 seconds to toast. 20 second to put in and out. And 6 seconds to turn them over. The 3rd piece will take 60 seconds to toast, 10 seconds to put in and out, and 3 seconds to turn over. 86 seconds + 73 seconds= 159
