If the distance between their eyes is 32 feet , how far is the child standing from his apartment building ? Round to the nearest foot .

Answers

You've got a leg and an angle next to it (and another, straight one, too), which is enough to calculate any side and angle of the triangle with some knowledge of trigonometry (in my country, you need to be in the last months of 9th grade or later to know that)
To calculate the other angle, you simply substract our known one (22) from 90. Nothing interesting here.
To calculate the hypotenuse, which is actually what is requested, you need to use the cosine of 22, which is about 0.9272, this way: h=l1/cos(L1), that means our distance is 32/0.9272, which is about 34.5131 ft (doesn't matter if there are feet, cm, inches, meters or whatever)

Answer:

30 Ft

Step-by-step explanation:

What is the selling price of a table ticketed at $1,234 with a 22% discount?A. $271.48
B. $962.52
C. $926.25
D. $1,000.00

Answers

Multiply $1,234 by 0.22 to find how much money you will be saving:

$1,234 x 0.22 = $271.48

Now, subtract this from the actual price to find the selling price:

$1,234 - $271.48 = $962.52

The selling price is B. $962.52

Answer:

Step-by-step explanation:

The selling price of a table ticketed at $1,234 with a 22% discount is $962.52. $1,234 x 0.22 = $271.48 $1,234 - $271.48 = $962.52

Keith exercises x hours a week. Troy exercises three hours less than Keith and Joe exercises two times more than Troy. Which expression represents the amount of time Joe exercises?A)
2(3x)
B)
2x - 3
C)
2x + 3
D)
2(x - 3)

Answers

If you would like to know which expression represents the amount of time Joe exercises, you can calculate this using the following steps:

Keith ... x hours a week
Troy ... three hours less than Keith: x - 3
Joe ... two times more than Troy: 2 * (x - 3)

The correct result would be D) 2 * (x - 3).

Answer:

The answer is D because

Step-by-step explanation:

Keith = x

And Troy exercises three hours less than Keith. Thus,

Troy = x - 3

And Joe exercises two time more than Troy. Thus,

Joe = 2(x - 3)

Two sides of an isosceles triangle have lengths of 6 inches and 15 inches,respectively.FInd the length of the third side.Explain your reasoning.

Answers

Answer:

The length of the third side is 15 inches.

Step-by-step explanation:

Generally in triangles, the longest side is opposite to the greatest angle. But for an isosceles triangle, two angles are equal and so two sides opposite to these angles. The two angles are greater than the third, so the opposite sides to the angles are equal and longer than the third side.

The answer is 15. Because an isosceles is a triangle wirh two equal sides, the side will have to be either 6 or 15. But for the triangle to fot the definition, the sum of two sides must be greater than the third. It couldn't be six because 6+6<15, but 15 works because 6+15>15.
