Answer: second option
Step-by-step explanation:
You know that it is a right triangular window frame.
Then, you can use the Pythagoren Theorem to find the lenght of the third side:
Where "a" is the hypotenuse (or the longest side), and "b" and "c" are the legs .
Then, you can solve for one of the legs:
Since you know the lenght of the hypotenuse and the lenght of one leg, you can substitute values.
Therefore, you get:
A ratio is an expression used to compare two quantities. A simplified ratio can be taken as is, but if a ratio has not yet been simplified, you should do so to make the quantities easier to compare and understand. In order to simplify a ratio, you divide both terms (both sides of the ratio) by the same number.
Answer:
Step-by-step explanation:
<em>Refer to picture.</em>
Let the distance to men are x and y and the distance between them is d.
The angle of depreciation is 27° and 30°, hence top angle of the triangle is 63° or 60°.
<u>Find the distance from the tower to men:</u>
- x = 20 tan 63° = 39.25 m
- y = 20 tan 60° = 34.64 m
<u>The distance between men is:</u>
- d =
<em>Note, all numbers are rounded</em>
Answer:
A
Step-by-step explanation:
solution is A.
A relation is a function if no x value gives two or more values of y though different values of x may give same value of y.
