I GIVE BRAINLIEST FOR EXPLANATION AND CORRECT ANSWER EXTRA POINTS 3
sveticcg [70]

Answer:

x=8

Step-by-step explanation:

The best way to go about this is to use a trig identity. You have the unknown opposite the angle and the hypotenuse, so its best to use the sine identity: sin(x)=\frac{O}{H}, where O is the opposite side, and H is the hypotenuse.

Set up the equation as:sin(27)=\frac{x}{17}, and solve for X.

I got x=7.718, rounded to x=8.

If I helped, a brainliest answer would be greatly appreciated!

bezimeni [28]

Answer:

log(6) = x

Step-by-step explanation:

4log(216)=12x

Divide both sides by 12

log(216)/3 = x

Use properties of logs

log(216^(1/3)) = x

Simplify

log(6) = x
