Math question

<p>there were two problems on the math portion that im still stumped on. One of them was an angle outside a circe intersecting it at a chord. It asked to find the biggest angle in the figure. the other asked to find the area of the trapezoid, but you werent given a length for the tob base i believe. Can someone guide me through how you found the solution to these problems?</p>

<p>For the trapezoid one, you make a rectangle in the trapezoid (which creates two triangles on each end). I think I then used the pythagorean theorem and did A = (1/2)(b1+b2)(h) and it ended up being 52.</p>
