Which set of values could be the side lengths of a 30-60-90 triangle?
jeyben [28]
If we say that side "a" is the shortest (adjacent), side "b" is the second shortest (opposite), and side "c" is the longest (hypotenuse): then angle A would be 30°,  angle B would be 60°, and angle C would be 90°

tan B = b/a
 or
a tan B = b

they have 4 as the smallest value in all four options, so we know that a=4

4 tan 60° = b
tan 60° = √3
so, 4 tan 60° = 4√3
b=4√3

that leaves two options left, so now we find "c":

c^2 = (a^2) + (b^2)
OR
c= \sqrt{a^{2} + b^{2}}

c= \sqrt{4^{2}+(4\sqrt{3})^{2}}

c= \sqrt{16+48} \\ c=\sqrt{64} \\ c=8

so a=4, b=4√3, and c=8

Making your answer B

Find the value of x. Will give brainliest.
s344n2d4d5 [400]
Since a line is equal to 180 degree
you pick one that has the variable x in it.
For example:  5x=180
180/5=36
therefore x=36
2. 6x=180
180/6= 30
x=30

a tank can hold up to 500 gallons of water.A gauge reading shows that it is at 80% of its capacity. How many more gallons can it
Paha777 [63]
So we start out by finding out what 80% of 500 is by,

500 * .80 = 400

So if 80% is 400 that means that there is still space available for 100 more gallons! 

How the heck did we know that?!? 

simple 500- 400= 100 

So that leaves us knowing that there are 100 gallons left that can be held!! :) 

                            So your answer is 100 gallons!! 

I hope that this helped!
