Answer:
The length of the shadow the telephone booth is <u>12 ft</u>.
Step-by-step explanation:
Given:
An adult elephant that is 10 ft tall casts a shadow that is 15 ft long.
The length of the telephone booth is 8 ft.
Now, to find the length of the shadow the telephone booth casts.
Let the length of the shadow the telephone booth be
As given, an adult elephant that is 10 ft tall casts a shadow that is 15 ft long.
So, 10 ft is equivalent to 15 ft.
Thus, 8 ft is equivalent to
Now, to get the length of the shadow of the booth we get cross multiplication method:
<em>By cross multiplying we get:</em>
<em>Dividing both sides by 10 we get:</em>
Therefore, the length of the shadow the telephone booth is 12 ft.
Recall:
The tan of the measure of an angle is the ratio of the opposite side to the adjacent side to that angle, that is :
.
Since this ratio is 3/y, we denote the opposite side, and adjacent side respectively by 3 and y.
(Technically we should write 3t and yt, but we try our luck as we see y in the second ratio too!)
Similarly,
.
The adjacent side is already denoted by y, so we denote the length of the hypotenuse by z.
Now the sides of the right triangle are complete.
