How to use law of sines when you have one solution

The video tutorial explains how to solve a triangle problem using the law of sines. It begins with converting degrees and minutes into decimal form, then applies the law of sines to find unknown angles and sides. The process involves calculating angle A using known side lengths and angles, followed by determining angle C by subtracting the known angles from 180 degrees. The tutorial concludes with a final calculation to find the remaining side length, emphasizing the importance of accurate calculations and understanding the law of sines.

How do you convert 15 degrees and 30 minutes into decimal form?

• 15.15 degrees

• 15.05 degrees

• 15.3 degrees

• 15.5 degrees

What is the law of sines formula used in this context?

• a/sin(B) = b/sin(A) = c/sin(C)

• a/sin(A) = b/sin(C) = c/sin(B)

• a/sin(A) = b/sin(B) = c/sin(C)

• a/sin(C) = b/sin(B) = c/sin(A)

Which function is used to find an angle from its sine value?

• Cosine function

• Inverse sine function

• Inverse cosine function

• Tangent function

How do you find the third angle of a triangle if two angles are known?

• Divide the two angles

• Multiply the two angles

• Subtract the two angles from 180

• Add the two angles

What is the value of angle A calculated in the video?

• 11.03 degrees

• 15.5 degrees

• 10.19 degrees

• 154.31 degrees

What is the final step in using the law of sines to find an unknown side?

• Add all sides

• Use the cosine rule

• Cross-multiply and divide

• Subtract known sides

What is the calculated length of side C in the triangle?

• 15.5

• 11.03

• 6.8

• 4.5
