GEOM 2 | Lesson 3 | Practice (Finding Angles) Solutions

1. \(\sin A = \dfrac{6000}{10,000}\)

\(A = \sin^{-1}\bigg(\dfrac{3}{5}\bigg)\) or \(∠A = 36.9˚\)

2.  \(\tan A = \dfrac{8}{6}\)

\(A = \tan^{-1}\bigg(\dfrac{4}{3}\bigg)\) or \(∠A = 38.7˚\)

3.  \(\cos A =\dfrac{1}{2}\); \(∠A = 60˚\)

\(\tan F = \dfrac{2}{3}\) or \(∠F = 33.7˚\)
