Question

Draw a triangle with sides a=6 b=8 c=10 label vertices A B C number 3

Answer 1

The Solution.

The triangle to be drawn must be a right-angled triangle since it is link with trigonometric ratios. So, below is the right-angled triangle:

By Trigonometrical Ratios,

`\sin A=\frac{opposite}{\text{Hypotenuse}}=(6)/(10)=(3)/(5)\text{ or 0.6}`

Similarly,

`\cos A=\frac{\text{Adjacent}}{\text{Hypotenuse}}=(8)/(10)=(4)/(5)\text{ or 0}.8`

Also, by Trigonometrical Ratio,

`\tan A=\frac{\text{opposite}}{\text{Adjacent}}=(6)/(8)=(3)/(4)\text{ or 0}.75`
