<h2>Answer :-</h2>
As we know that,
Pythagoras triplet
1) a² + b² = c²
Let


<h3>Hence, A can't be Pythagoras triplet</h3>
2) a² + b² = c²


<h3>Therefore, B can be Pythagoras triplet</h3>
3)a² + b² = c²


<h3>Hence, C can't be Pythagoras triplet</h3>
4) a² + b² = c²


<h3>Hence, D can't be Pythagoras triplet</h3>
<h2 /><h2>Therefore :-</h2>
Only B can be Pythagoras triplet.
Answer:
8
Step-by-step explanation:
Hi! So, here’s what I know. Every triangle will equal to 180*. So to check if that triangles is 180 we add all angles and it should add up to 180*.
Now the question is, Why it shows that the angles of a triangle equal to 180* when added up?
Note that we see all angles lie on a straight line, therefore we know that when we add angles that lie on a straight line it will equal to 180*, they will also meet at the same point.
This is all I can help with. Hope it helped something!!! Have a great day!
