2, sin( θ )=6/12=1/2 => theta=30 degrees.
=> triangle is 30-60-90

3.
Cos(45)=sqrt(2)/2
=> x=10*sqrt(2)/2=5sqrt(2)

<h3>Answer: C) 70 degrees</h3>

=========================================================

Explanation:

We have n = 6 sides, so the interior angles must add to 180(n-2) = 180(6-2) = 720 degrees

Lets add up the angles, set the sum equal to 720 and solve for x

x+2x+115+2x+115+2x = 720

7x+230 = 720

7x = 720-230

7x = 490

x = 490/7

x = 70

This makes angle 2x = 2*70 = 140 degrees

We see that x = 70 is the smallest angle, so that's why C is the answer.
