When provided two angles use the law of sines to find the missing values

The video tutorial covers the basics of triangle geometry, emphasizing the sum of angles in a triangle. It introduces the law of sines and explains how to apply it to solve for missing sides and angles. The tutorial demonstrates solving for side C and side A using cross multiplication and original ratios, highlighting the importance of using a scientific calculator for accurate results.

What is the sum of all angles in a triangle?

• 90 degrees

• 360 degrees

• 180 degrees

• 270 degrees

What is required to apply the Law of Sines?

• A right angle

• Three known angles

• Two equal sides

• A ratio with one angle and its opposite side

When is cross multiplication used in solving proportions?

• When solving a proportion

• When dividing fractions

• When adding fractions

• When subtracting fractions

What is the approximate length of side C when calculated using the Law of Sines?

• 56.23

• 54.23

• 58.23

• 60.23

Why is it important to use the original ratio when solving for another side?

• To avoid rounding errors
