Stuff & nonsense, tri, the student is expected to calculate the exact value of HF (that's why the numbers have been chosen to make that such a simple matter)!It is not required to calculate the exact value of HF as it has to be greater than HG or FG. Only one option fits in this condition.
I tried doing what you said and my answer is the 4th optionBy Pythgoras: HF2 = HG2 + FG2. So, what does HF equal?
\(\displaystyle SIN = \frac{OPP}{HYP} \left(\text{ie: }\frac{FG}{HF}\right)\). So, which answer is correct for Sin H?

If this were a question on something like the SAT I'd agree that it's a good test taking strategy. But since we are here to help the OP answer the question it's better to focus on the method, not time saving strategies.It is not required to calculate the exact value of HF as it has to be greater than HG or FG. Only one option fits in this condition.
