M4 Law of sines

Which one is the easy way to remember trigonometric ratios?

• Sah Coh Toa
• Soh Cah Toa
• Soh Cah Tao
• Soh Ceh Toa

What is the measure of angle A?

• 58 degrees
• 61 degrees
• 78 degrees
• 74 degrees

Identify the Law of Sines

• Sin²x + Cos²x =1
• Sin(A)/a = Sin(B)/b = Sin(C)/c
• Sin(A)Sin(B)Sin(C) = 1
• Soh-Cah-Toa

solve the triangle:
A=65 C=65 a=12

• B=50, b=9.9, c=12
• B=50, b=10.1, c=12
• B=70, b=12.8, c=12
• B=40 b=11.2, c=12
