16. Prove that the followings: (a) (sin 75 degrees - cos 75 degrees)/(cos 15 degrees + cos 75 degrees) = 1

Someone me! if you’re smart you can solve this!

Solve each equation using the quadratic formula. find the exact solutions. 6n^2 + 4n - 11

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
