Answer: C) 12.2
================================================
Explanation:
We have a known adjacent side (10) and an unknown hypotenuse (x). The cosine rule ties the two sides together.
cos(angle) = adjacent/hypotenuse
cos(35) = 10/x
x*cos(35) = 10
x = 10/cos(35)
x = 12.2077458876146 approximately
x = 12.2
Make sure your calculator is in degree mode.
All sides are equal in an equilateral triangle and the perpendicular bisects the side too.
so BC will be bisected and the segments be 5 each.
you can use Pythagoras theorem to find the altitude length, hypotenuse will be one side of the triangle.

$h^2=100-25=75$
$h=\sqrt{75}=5\sqrt3$
