Question

PLEASE HELP!!

Triangle not drawn to scale
Given: m & B = 18°, b = 9, and c = 20. Find
m & Co to nearest whole number.

Answer 1

43°

Explanation:

Calculating for the measure of angle C using

sine rule

`(sin18)/(9) = (sinc)/(20) \\ sinc = (sin18 * 20)/(9) \\ sinc = 0.6867 \\ c = \csc(0.6867) \\ c = 43.3869 \\ c = 43 \: degrees`
