1. angle A = 69.3°
2. angle B = 20.7
3. AB = 17
4. BC = 15.9
5. AC = 6
Trigonometric ratios are mathematical expressions relating angles and sides in a right triangle.
Common ratios include sine (opposite/hypotenuse), cosine (adjacent/hypotenuse), and tangent (opposite/adjacent).
Since Cos A = 6/17 = adj/hyp
adj = 6
hyp = 17
opp = √17² -6²
= √ 253
= 15.9
1. cos A = 6/17 = 0.353
A = 69.3°
2. angle B = 90 - 69.3
= 20.7°
3. AB = hypotenuse = 17
4. BC = opposite = 15.9
5. AC = adjascent = 6
