Answer: x = 4
Step-by-step explanation:
You basically want to solve for the angle A. Do arcsin of 1/3, which is approximately 19.47 degrees. In this triangle, we are missing the adjacent and opposite, but we do have the angle luckily. Lets use SOH-CAH-TOA.
We can see here that doing sine will give us the length of the opposite
. Do sine of 19.47, then multiply by 12. I got 4
Answer: 8(8+x)=80
Step-by-step explanation: 8 times is shown in parenthesis, 8+x is the sum, and 80 is the answer
4x - 26 = 3x + 4
-3x -3x
x - 26 = 4
+26 +26
x = 30
Since the 2 angles are opposite of each other you would set them equal to each other.
The measure of any interior angle of a convex regular n-gon is :
180 º - ( 360 º / n )
For a 30-sided polygon,
interior angle = 180 º - ( 360 º / 30 )
..................... = 180 º - 12 º
..................... = 168 º
