In 30-60-90 triangle there is a rule that leg opposite to 30 degree angle is 2x shorter than hypotenuse. That means that shorter leg is 10 feet long.
longer leg we can calculate using Pythagoras theorem.
20^2 = 10^2 + x^2
x^2 = 300
x = √300 = 10√3
Answer:
1.5 as a fraction is written as 3/2
Step-by-step explanation:
The ratio 1.5 which is read "1.5 to 1" means that the length is 1.5 times the width. So, for example if your paper is 2 inches in width then the length is 1.5 × 2 = 3 inches.
Here is the first sign that should tell you this isn't a rectangle.
d=_/w^2+l^2 is the equation to solve the diagonal of a rectangle
if you plug in 21 and 20, d would equal 29 not 28 so for that reason alone it is not a rectangle.
I am about 90% sure the correct answer is B. I hope this helps let me know if I was right.
