Answer 2

$\triangle ABC$ is the required triangle.

Step-by-step explanation:

Given,

Construct $\triangle ABC$ where the base $BC=5.7\ cm$,$\angle B =30\ degree$ and difference between other two sides $AB-CA=3\ cm$

Following steps:

• Draw a line segment $BC=5.7\ cm$ using scale.
• At point $B$, draw angle $30\ degree$ using protector like $\angle CBX=30\ degree$
• Cuts $BD=3\ cm$ ($AB-CA=3\ cm$) and join $CD$
• Bisect the line $CD$ where it's cuts at point $A$ as shown in figure.
• Join $AC$

Now, $\triangle ABC$ is the required triangle.
