Geom Final Exam Part 1

Set up the problem so that you can solve for X.

• sin X = 41/28

• tan X = 41/28

• cos X = 28/41

• sin X = 28/41

What is the length of y in this picture?

• 45
• 5√2
• 90
• 5

Which of the following formulas shows the Law of Cosines?

• c² = a² + b² - 4ac + cosA
• c² = a² - b² - 2abcosC
• c² = a² + b² - 2abcosC
• (cos A)/a = (cos B)/b

Identify the Law of Sines

• $\sin^2x+\cos^2x=1$

• $\frac{\sin\left(A\right)}{a}=\frac{\sin\left(B\right)}{b}=\frac{\sin\left(C\right)}{c}$

• $\sin\left(A\right)\sin\left(B\right)\sin\left(C\right)=1$
