Applying Ratios to Triangles

If two triangles satisfy the SSS Similarity Theorem, what can you say about their corresponding angles?

• Their corresponding angles are parallel.

• Their corresponding angles are perpendicular.

• Their corresponding angles are equal.

• Their corresponding angles are congruent.

Use the Law of Sines to find the value of x to the nearest tenth.

Two stakes are holding a small blimp in place. Stake A measures an angle of elevation of 49^o and Stake B measures an angle of elevation of 58^o. If the string attached to Stake A has a length of 148 feet, what is the length of the string attached to Stake B?

• 152.7 feet

• 166.3 feet

• 157.3 feet
