Answer:
The last one .
Step-by-step explanation:
1) There are three trigonometric ratios for right-angled triangles.
In a right triangle, the hypotenuse, h, is the side opposite the right angle. Relative to the acute angle θ, check the attachment, the legs are called the opposite side, o, and the adjacent side a.
2) In this case, we are given a length and an angle to find x and y.
Let's find x first. To find x we need to use .
Find y.
Notice that, we can use the Pythagorean Theorem to find y.
3) Round them off to the nearest tenth.
Therefore, the correct choice is the last one .
Answer:
D. 6<x<24.
Step-by-step explanation:
Let x be the length of third side of our triangle.
We have been given that two sides of a triangle have lengths 9 and 15.
To find the possible length for 3rd side of our triangle we will use triangle inequality theorem.
Triangle inequality theorem states that the sum of the lengths of any two sides of a triangle should be greater than the length of the third side.
Using triangle inequality theorem we will get:
Therefore, the third side of triangle must be greater than 6 and less than 24 and option D is the correct choice.
I take it that you're trying to solve for the variable (x), so by using the order of operations (PEMDAS), the first step is to add 40 to both sides of the equation as addition cancels out subtraction.
From there you will divide by -32 and simply the fraction.
I hope this helps, but please let me know if this is not what you're trying to do.
