Question
Find the missing side.
- 7.44
- 26.33
- 13.27
- 1.45
Hint:
tan x° = opposite / adjacent
The correct answer is: 7.44
The missing side can be estimated using trigonometric ratios. Therefore,
tan x° = opposite / adjacent
tan 28° = z /14
tan 28°= 0.531
0.531 = z / 14
z = 0.531 x 14
z = 7.44
sin x° = opposite / Hypotenuse
cos x° = adjacent / Hypotenuse
sin x° = opposite / Hypotenuse
cos x° = adjacent / Hypotenuse
