What is the length of AB?

AB = 4

Step-by-step explanation:

This is a 30-60-90 triangle, so we apply the rules of a 30-60-90 triangle to the problem

if base CB=2, then hypotenuse AB is double the base CB

AB= 4

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
