The tangent of an angle in a right-angled triangle is the ratio of the length of the opposite side to the length of the adjacent side.
Tangent (θ) = Opposite / Adjacent
1. Consider the right-angled triangle below. If the side opposite to angle A is 8 units and the side adjacent to angle A is 6 units, what is the tangent of angle A?
2. In a right-angled triangle, if the opposite side is 12 and the adjacent side is 5, the tangent of the angle is .
3. Which of the following ratios represents the tangent of an angle?
Hypotenuse / Opposite
Adjacent / Hypotenuse
Opposite / Adjacent
Opposite / Hypotenuse
4. The tangent function is only applicable to right-angled triangles.
True
False
5. In a right-angled triangle, if angle B is the reference angle, and the side opposite to B is 15 units and the side adjacent to B is 20 units, calculate the tangent of angle B.
