## anonymous 3 years ago What is the value of w?

I have come to the conclusion that w is also 7√3 because of the 30,60,90 theorem.

3. anonymous

so yeah, your right the triangle is a 30 60 90 triangle. now do you know what the theorem states?

4. anonymous

Yes. I believe the pattern is to find the hypotenuse and the long leg.

5. anonymous

so you can chek this website out: http://www.mathwarehouse.com/geometry/triangles/right-triangles/special-right-triangles.php see if it helps you?

6. anonymous

then if you have anymore questions please post them?

7. anonymous

we know from the sketch that Cos(30)=(7/root (3))/w then you can make w the subject of the formula . Done

8. anonymous

Wait. $Cos30 =7/\sqrt 3 / w = 14$

9. anonymous

Is that right?

w=7/(sqr(3)cos(30))
