I see the cosine in problem 7 and I see the cotangent in problem eight. So I know that you're talking about trig functions in class. Problem 9 is trying to find out if you know what they're good for. You have a right triangle and you know the lengths of all three sides. So you can easily find the sine or the cosine or the tangent or the cotangent of the angle. Pick one and calculate the number. Then use your calculator to find the angle that has that number for the trig function that you chose.
Answer:
Step-by-step explanation:
<h3>
The missing figure is attached.</h3>
For this exercise you can use the following Trigonometric Identity:
Let be "x" the hypotenuse of this right triangle.
You can identify from the figure that, in this case:
Then, knowing these values you can substitute them into :
Finally, you need to solve for "x" in order to find the lenght of the hypotenuse.
This is:
For this question you should know that 3.5 = 35/10 and 3/5 = 9/10 so you can see that 35/10 is not as same as 9/10 :)))
i hope this is helpful
have a nice day
Answer:
x = 3
Step-by-step explanation:
To find the value of x. We have to use Exterior Angle Theorem.
It is says "The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle."
In the given figure,
45x = 25x + (57 + x)
Now let's find the value of x.
First we need to isolate the variable terms
45x - 25x = 57 + x
20x - x = 57
19x = 57
x = 57/19
x = 3
The value of x = 3.
