Question

Aeuclid has a triangle in mind. Its longest side is 20 units and another on its side is 10 units long its area is 80 what is length of third side

Answer 1

Answer:

Step-by-step explanation:

Area=80=20 h2

This tells us

h=8

Now let's split the given triangle into two right triangles with a common side, h, and apply the Pythagoras theorem to each.

a=102−h2−−−−−−−√=6

20−a=14

x=h2+142−−−−−−−√=64+196−−−−−−−√
