To figure this out, use the acronym SOHCAHTOA to determine which trigonometric function to use.
8 is opposite to <R and 3 is adjacent to <R so we use tangent.
Set up the following equation: tan(x)=8/3
Find the inverse (aka. tan^-1): x=69.44
So your answer is <R=69.4 degrees

Answer: X is less than 3
Step-by-step explanation:
4x - 7 < 5
Add 7 to both sides:
4x < 12
Divide both sides by 4:
x < 3
250 you have to divide, btw im hella wrong
