This right triangle with 30°, 60° and 90° is called semi equilateral. Its particularity is that the side opposite to 30° is equal half of the hypotenuse.

Here the longest leg is nothing but the hypotenuse =18.(given):
Let  x be the side opposite to 60° and let's calculate it by Pytaghoras:

18² =(18/2)² + x²,

324 = 81 + x² . Subtract 81 from both sides

324 - 81 = 81 + x² - 81

243 = x² and x = √243 =9√3

1. -1/5>-3/5 because we have like denominators we compare the inputs by the numerators.

2. 3/4 > 5/8 the least common denominator is: 8

Rewriting as equivalent fractions with the LCD:

                                   3/4 = 6/8    5/8 = 5/8

Comparing the numerators of the equivalent fractions we have:

                                   6/8 > 5/8
