Answer:
9.1 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions.
We want to find x, which is opposite the angle and we know the hypotenuse.
We can use sin theta, which is the opposite side over hypotenuse.
sin theta = opp /hyp
sin 49 = x/12
12 sin 49 =x
9.05651=x
To 1 decimal place
9.1 =x
