What is the length of side x?

x = 3

Step-by-step explanation:

In a 30-60-90 triangle the side between 60 and 90 degree angle is  a, the side between 30 and 90 degree angle is  a√3, and the hypotenuse is 2*a.

Given that the side that is supposed to be  a is currently √3, we know that the missing side x must be:

a√3    (We know that a, in this case, is √3, so substitute)

x = (√3) * (√3)

x = 3

they are simplified

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
