THE LAW OF SINES AND COSINES
JEOPARDYMrs. BELCHER
Math 4
Directions• Each person should work out every
problem on their paper• Rotate through your group who works
the problem on the white board and displays the answer to earn points
• Don’t hold up your white board until I ask for them
• Every team that gets the correct answer earns points
• Each team needs to keep their own score

KEEP ON A SOLVIN’ 100• In order to solve the triangle given
b = 40, c = 45, and A = 51°, which equation should you use first to solve.
A. a² = b² + c² - 2bc·cos AB. b² = a² + c² - 2ac·cos BC. c² = a² + b² - 2ab·cos CD. Law of Sines
KEEP ON A SOLVIN’ 200• If B = 41°, C = 52°, and c = 27,
