no your answer is wrong. the answer is 15.6

Step-by-step explanation:

the side opposite to 30 degree angle is half of hypotenuse( I. e half of 18 that is 9)

the side opposite to 60 degree angle is √3/2 the hypotenuse.

that is √3/2 * 18

that is √3 * 9

that is 1.73 multiplied by 9 .....(as value of √3 is 1.73)

that is 15.57

rounding it to the nearest tenth it becomes 15.6
