We are trying to find the length of the side opposite to the 20 degree angle. We are given the hypotenuse, so we can use the trigonometric function sine to solve for x.
sin(theta) = opposite / hypotenuse
sin(20) = x/18
18sin(20) = x
x = 6.1564
The answer to the nearest tenth is 6.2

Okay well the last number is in the thousandths place so put 216 over 1000. 216/1000. Now to simply. Find the biggest common denominator. the biggest common denominator is 8. So now you divide: 216÷8=27, 1000÷8=125 now put 27/ 125. ANSWER: 216/1000=27/125
