"How are we ever going to build this bridge?" asks Omkar looking out across the raging river. "Let's start by finding the distance to the big rock on the other side." Melissa replies. Moving 100
meters along the river, Melissa looks back and measures the angle between Omkar and the big rock: 3 3 ∘ 33 ∘ 33, degrees. Melissa then instructs Omkar to measure the angle between Melissa and the big rock. From his vantage point, Omkar sees an angle of 9 8 ∘ 98 ∘ 98, degrees between Melissa and the big rock.
