Question 1070656

This problem refers to triangle ABC.

If b = 4.1 m, c = 7.4 m, and A = 118°, find a. (Round your answer to one decimal place.)
<pre>Correct LAW to use: Law of Cosines, which leads to the following formula: {{{a^2 = b^2 + c^2 - 2bc * Cos A}}}
The only UNKNOWN variable is "a," the one you need, and which is the side opposite &#8736A.
Round to one (1) decimal place, as requested.
