Example: Find m∠L to the nearest degree in ∆LMN if n = 7, l = 9, and m∠N = 43.
Example: Solve ∆DEF if m∠D = 112, m∠F = 8, and f = 2. Round angle measures to the nearest degree and side measures to the nearest tenth.
Example: Solve ∆HJK if m∠J = 32, h = 30, and j = 16. Round angle measures to the nearest degree and side measures to the nearest tenth.
Example: Three cities form the vertices of a triangle. The angles of the triangle are 40°, 60°, and 80°. The two most distant cities are 40 miles apart. How close are the two closest cities to the nearest tenth of a mile?
