b = √?

Answer 1

Pythagorean Theorem.

Answer 2

Couldn't you use trigonometry?

Answer 3

No Pythagorean... find angle B, and then use the SINES LAW.

Answer 4

I think what you gotta do in here is a special right triangle.Which is equal 30,60,90

Answer 5

@joshhfers or you could use that.

Answer 6

How haven't I though about this? , @joshhfers, nice !!!! and the proportionsa are a, a√3, 2a
respectively from smallest to largest side.

Answer 7

Well, @slumberousteenager show us some effort please.

Answer 8

there you go if it is easier for you

Answer 9

still lost.

Answer 10

let us use the 30-60-90 rule

notice one angle is 60 degrees, there's another angle given, the 90 degrees one

so we have 60 and 90, what would the remaining angle be? well, 60+90 = 150
if all internal angles should add up to 180, all that's left is 30

so is a 30-60-90 triangle, thus we'd use the 30-60-90 rule -> http://img.sparknotes.com/content/testprep/bookimgs/sat2/math2c/0003/306090.gif

so based on that rule template. what do you think is "b"?
