Given tan θ = 3/4 for acute angle θ, find the value of a and b for the statement cos θ = a/b.

Furkat [3]

Step-by-step explanation:

$\tan \theta = \frac{3}{4} \\ \\ \sec \theta = \sqrt{1 + { \tan }^{2} \theta} \\ \hspace{22 pt} = \sqrt{1 + {( \frac{3}{4} )}^{2} } \\ \hspace{22 pt} = \sqrt{1 + {\frac{9}{16} }} \\ \hspace{22 pt} = \sqrt{ {\frac{16 + 9}{16} }} \\ \hspace{22 pt} = \sqrt{ {\frac{25}{16} }} \\ \red{ \boxed{\bold{ \therefore \sec \theta = { {\frac{5}{4} }} }}} \\ \\ \cos \theta = \frac{1}{\sec \theta } = \frac{4}{5} = \frac{a}{b} \\ \\ \implies \: a = 4 \: and \: b = 5$

We can set up a proportion.

2/3 = x/1

Cross multiply.

2 * 1 = 2. 3 * x = 3x, so we have 3x = 2.

Now we can divide 3 by 2 to get our answer, which is 1.5. :)
