the angle of depression is measured from the top of a 43 ft tower to a reference point on the ground. its value is found to be 6

Dafna1 [17]

An angle of depression is the angle of a slant to the upper horizontal line. The official definition is: the angle formed by the line of sight and the horizontal plane for an object below the horizontal.

Thus, for this problem, we must use trigonometry. The tower is perpendicular to the upper horizontal and the ground, so after we draw a line connecting the points we get 90 - 63 = 27, which is one of the angles in the right triangle.

The other angles are ninety and 63. We wish to find the measure of the bottom of the triangle, so we use tangent which includes both legs.

Therefore, tan(27)=x/43. Plugging this into a calculator, we get roughly 21.9.

Hope this helped! It probably sounds a lot harder than it actually is without a picture.

Alenkinab [10]

Answer:

yearly cost for housing expenses = $11,400, average monthly cost for food = $650

yearly clothing cost = $900,

average monthly cost for transportation= $500,

Yearly cost for insurance & medical= $14,400

yearly cost for emergency fund = $600

average monthly college saving = $50

Step-by-step explanation:

Yearly housing = monthly cost * 12 = 950 * 12 = 11400

Food, monthly = 7800 /12 = 650

Clothing, yearly = 75 * 12 = $900

Monthly transport = 6000 / 12 = $500

Insurance and medical = 1200*12 =14400

Emergency fund = $50 * 12 = $600

College saving = $600 / 12 = $50

A commercial jet and a private airplane fly from Denver to Phoenix. It takes the commercial jet 1.1 hours for the flight, and it

FinnZ [79.3K]

Answer:

The speed of the private airplane is 770 mph, the speed of the commercial airplane is 980 mph.

Step-by-step explanation:

Let x mph be the speed of private airplane. If the speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane, then the speed of commercial airplane is (x+210) mph.

It takes the commercial jet 1.1 hours for the flight, then it covered the distance of

$1.1(x+210)\ miles$

It takes the private airplane 1.8 hours for the flight, then it covered the distance of

$1.8x\ miles.$

The distances are the same, so

$1.1(x+210)=1.8x\\ \\1.1x+231=1.8x\\ \\1.8x-1.1x=231\\ \\0.7x=231\\ \\7x=2,310\\ \\x=770$

The speed of the private airplane is 770 mph, the speed of the commercial airplane is 770 + 210 = 980 mph.
