Answer:
x=3.11
Explanation:
Sin 15 degrees = x/12
multiply 12 on both sides to get rid of the denominator
now you have 12 times the sin of 15 degrees = x
which can also be written as 12 sin 15 = x
put 12 sin 15 into your calculator and you get 3.105828541 or just 3.11 when rounded to the nearest hundreth
