GEOM 2| Lesson 3|Practice 2 Solutions

a.  \(cos A = \frac{6000}{10,000}\)

\(A = cos^(-1)\frac{3}{5}\) or \(∠A = 53.1˚\)

b.  \(sin A = \frac{6000}{10,000}\)

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

2.  \(tan A = \frac{8}{6}\)

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

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

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