Using tables, find the acute angle θ, when:

(i) tan θ = 1.476

(ii) tan θ = 2.91

(iii) tan θ = 0.3

In ΔABC, if AC = 17 m and BC = 8 m, then tan A =

1. $\Big(\dfrac{8}{15}\Big)$

2. $\Big(\dfrac{15}{8}\Big)$

3. $\Big(\dfrac{8}{17}\Big)$

4. $\Big(\dfrac{15}{17}\Big)$

If sec θ = $\Big(\dfrac{25}{7}\Big)$, then the value of cot θ is:

1. $\Big(\dfrac{25}{24}\Big)$

2. $\Big(\dfrac{24}{7}\Big)$

3. $\Big(\dfrac{7}{24}\Big)$

4. $\Big(\dfrac{24}{25}\Big)$

The value of (1 + tan²θ)(1 − sin θ)(1 + sin θ) is:

1. 0

2. 1

3. sec²θ sin²θ

4. cot²θ
