Step-by-step explanation:
We know that:
And we want to find:
Remember that there is a trigonometric identity that relates the 
function with the function
Then if this means that:
Finally:
The correct answer is C. Goodluck
Answer:
Yes, the sum of any two lengths is greater than the third length
Step-by-step explanation:
we know that
The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
In this problem
Applying the Triangle Inequality Theorem
1) 9+5 > 8 ----> is ok
2) 8+5 > 9 ---> is ok
3) 8+9 > 5 ---> is ok
therefore
Yes, the sum of any two lengths is greater than the third length
Answer: x=55 y=145
x=55
35+90=125
125-180=55
y=145
180-35=145
I hope this is good enough:
Answer:
<h2><u>
r = -0.4</u></h2>
Step-by-step explanation: 57.7r + 23.23 = 2.57 57.7/57.7 = -20.66/57.7
- 23.23 - 23.23
57.7r = -20.66
