When it comes to dividing decimals, bear in mind that, first off you'd want to do away with the decimal point.
now, "you add as many zeros to the other term, as it has decimals", what the heck does that mean?
for example 2.135 ÷ 5
notice, the 2.135 has three decimals, namely three numbers to the right of the decimal point.
since 2.135 has three decimals, then what we do, we add three zeros to 5, AND do away with the decimal point, thus our division is really
2135 ÷ 5000, which is 0.427
now, if we had 2.135 ÷ 5.79
what we do is, since 2.135 has three decimals, we add three zeros to 5.79, and since 5.79 has two decimals, we add two zeros to 2.135, then our division is really
213500 ÷ 579000 <-- notice, no dot on both
which is about 0.3687392
anyhow, that said, check the picture below

Answer:
x = 9
Step-by-step explanation:
This shape is a 30-60-90 triangle, which means that the angles of the triangle are each 30°, 60° and 90°. Given that the measures of the angles of the triangle are known, as well as one side, we can find the measures of all the other sides (example attached). A 30-60-90 triangle is special because of the relationship of its sides. The hypotenuse (directly across from the 90° angle) is equal to twice the length (2x) of the shorter leg, in this case labeled 'x' and directly across from the 30° angle. The longer leg, across from the 60° angle, is equal to multiplying the shorter leg (x) by √3 or x√3.
Since the measure of the hypotenuse is given at 18, we can set the expression of that side equal to 18 and solve for x:
2x = 18 or x = 9
