A Use sine, cosine, tangent, and the Pythagorean Theorem to solve for angles and lengths
B Use complementary and supplementary angle rules only, with no trigonometric functions
C Use scientific-notation conversion to compute the side lengths
D Use standard deviation and variance formulas to solve for the angle
