Question

draw angle of 20 degree with ruler ,pencil and rounder and it is possible do it as challenge​

Answer 1

Answer:

Draw a right triangle with Length 10 and height 3.64 cm. The smallest angle is 20 degrees.

Step-by-step explanation:

Triangles are easy to draw and they have angles. We know some trigonometry and we want an angle of 20

Let's use SOH CAH TOA.

Tangent of 20 degrees equals the opposite side over the adjacent side.

Tan 20= 0.3639.

So why not just use a ruler to draw out a right triangle with a length of 10 units (centimeters is good) And a height of 3.64 units.
