Answer:
x = 10
Step-by-step explanation:
By looking at the picture, I can tell the angle of the 3x is also 30 degrees.
This means 3x = 30.
When you solve for x by dividing each side by 3, you result with the answer of x = 10.
To check you work, plug in 10 for x to recieve 30 degrees again.
Answer:
it is in quadratic equation meaning you use Plus or minus
Answer:
10
Step-by-step explanation:
We will use trigonometry to solve this problem.
We see that the side provided is the hypotenuse and the side we are looking for is opposite to the angle provided. Thus, we will use sin since sin uses opposite/hypotenuse.
Now we solve.
sin45 = x/14
sin45 * 14 = x
x = 9.899494936611665
Answer:
new signs are needed.
Step-by-step explanation:
Given: A 
-kilometer section of a highway is designated as a scenic byway. New signs will be placed at the beginning and end of this section and at every 
Km in between.
To find: How many new signs are needed?
Solution:
We have,
A -kilometer section of a highway is designated as a scenic byway.
New signs will be placed at the beginning and end of this section and at every Km in between.
So, there are 
signs placed, one at the beginning and one at the end.
Now, in between these signs there will be 
signs.
Hence, the total new signs that are needed is 
.
First you had to used their apply complex arithmetic rule.
Then you had to refine by equation.
Finally, refine again by equation.
Final answer: 
Hope this helps!
