- Finding the Tangent by Drawing and Measurement
Example 1.2.1:
By drawing and measurements find the size of the angles to the nearest degree whose tangents are:
(a) \( \frac{3}{5} \)
(b) \( \frac{3}{8} \)
(c) \( \frac{7}{20} \)
Solution
(a) \( \frac{3}{5} \)
Tan θ = \( \frac{3}{5} \)means opposite is 3 cm and adjacent is 5 cm
The lengths of the opposite and adjacent are in the ratio 3 : 5.
