Use the cosine ratio, as you have the adjacent and hypoteneuse.
So, set up cos50=2/x, but with the variable on the bottom,the cos50 and x switch places
x=2/cos50
x=3.11
Answer:
In the pics
Step-by-step explanation:
Srry about the messy sketches
hope you got the general idea
if not :
Each figure got it's own sum of its angles. All I did was to sum all the given angles and made it equal to that number(360/540/720).
As a result, I found the value of the variable and after that the angles themselves.
The correct answer is B. 8<=l<=10. You can find this because we know the length is 2 feel more than the width, so when the length is provided, we can find the area. 8*6 is 48, which is the minimum area, and 10*8 is 80, which is the maximum area allowed.
Okay so first of all you have to divide the -6 that’s in the parenthesis because it’s by itself. Then when you divide it you should have k by itself and your final answer would be 2.
Hope that helps!
