Bob says that he can find the area of the triangle below using the formula: A =
%7B2%7D" id="TexFormula1" title="\frac{1}{2}" alt="\frac{1}{2}" align="absmiddle" class="latex-formula"> * 8 *18 * sin (120°). Is he correct? Explain why or why not.
1 answer:
Answer:
No.
Step-by-step explanation:
No, Bob is not correct.
The formula he's using is the following:
The important thing here is that the angle is between the two sides.
In the given triangle, 120 is not between 8 and 18. Therefore, using this formula will not be valid.
Either Bob needs to find the other side first or find the angle between 8 and 18.
