120/12=x
120/12=10
Then answer to this problem is B
Answer:
y = 6.22
You can solve this in two ways.
1.) Use SOH CAH TOA:
I typically start off by labeling the sides of the triangle with H (hypotenuse), O (opposite), and A (adjacent). Because I need to figure out what y is when given an angle and 4, I will use CAH, or cosine.





2.) Use Law of Sines:
Solve for the last angle inside the triangle first.

Then use the angle you found (40°) in the equation.



Answer:
63.5
Step-by-step explanation:
using soh-cah-toa, you can determine that the x and the value given are sin(theta). Sin is opposite over hyp.
thus,


once you solve that you get the angle x equals to 63.4746 which can be rounded to 63.5°
hope this helps!
