<h2>Answer:</h2><h3>C. The hypotenuse is twice as long as the shorter leg. </h3><h3>B. The longer leg is √3 times as long as the shorter leg.</h3><h3 /><h2>Step-by-step explanation:</h2>
A 30-60-90 triangle is a right triangle. Triangles with a right angle are called right triangles. A right triangle can only have a right angle. The representation of this problem is shown below. So let's demonstrate why the mentioned options are correct:
The hypotenuse of a right triangle is always opposite to the right angle. If we name as the shorter leg, for the sine of law is true that the hypotenuse is:
So this fact tells us that the hypotenuse is twice as long as the shorter leg
The longer leg, let's name it can be calculated using Pythagorean Theorem:
So it is true that the longer leg is √3 times as long as the shorter leg.
Move the decimal place enough to the right to create 3.28. This takes 4 movements, which would be 
. Expressions less than 1 have a negative power when put into scientific notation.
From there, put it into the right form:
