If a = 20 mm, b = 12 mm, and m∠C = 80°, what is the approximate area of ABC?
Lana71 [14]

Answer:

118.18 mm^2

Step-by-step explanation:

Sides <em>a</em> and <em>b</em> form angle C, so the information given is a side-angle-side (SAS) problem.

Use the formula A=\frac{1}{2}ab\sin{C}.

A=\frac{1}{2}(12)(20)\sin{80^\circ} \approx 118.18 \rm \,mm^2
