<span>3.25 mm = 3.25 cm, 30 cm = 12 inches. So, 12/30 x 3.25 = 1.3</span>
The value of cos x⁰ from the information given is; g/h.
<h3>What is the value of cos x⁰?</h3>
According to the task content;
- The value of cos x° from the information contained in the task content is required.
From conventional Trigonometry;
- It follows that tan x = sin x/cos x.
On this note, it follows that;
cos x⁰ = sin x⁰/tan x⁰.
cos x⁰ = 6/h ÷ 6/g
cos x⁰ = g/h
Ultimately, the value of Cos x⁰ by evaluation is g/h.
