This is the concept of trigonometry, the value of x will be calculated as follows;
sin theta=[opposite]/[hypotenuse]
theta=x
opposite=16 units
hypotenuse=21 units
thus;
sin x=16/21
hence;
x=arcsin(16/21)
x=49.63
x=50 (to the nearest degrees)
80 because since the ones number is 5 or higher.
34/18 = 1.89
1 5/6 = 1.83
34/18 is greater then 1 5/6
The answer is 15 because every yard is 3 feet
