Kyung is building a triangular pool in his backyard. he knows that side f is 12 m and that both angles g and f are 40°, which means that angle d is 100°. what is the length of side d? round the answer to the nearest tenth. 7.6 m 7.8 m 18.4 m 19.0 m

Since you know the length of a side (side f) and the measure of its opposite angle (<F), you have enough information to establish the ratio used in the law of sides. Since you also know the measure of angle D, you can find side d.

18.4 m

The answer is C. 18.4
