Question

AB = 7 and AC = 17. Find angle B to the nearest degree.

Answer 1

OK we have a right angle A and we're interested in angle B.

Relative to B, AB=7 is the adjacent side and AC=17 is the opposite side so we have:

`\tan B = \frac{\textrm{opp}}{\textrm{adj}} = (17)/(7)`

`B = \arctan (17)/(7) \approx 67.62 ^\circ`

Answer: 68
