Question

Given a triangle with A=130 degrees, a=10cm, b=10cm, How do you find side c and the two other angles, big B and C?

Answer 1

The described triangle is impossible and therefore there is no possible solution.

Explanation:

Since `a=10" cm"=b`
`rarr /_A =130^@=/_B`
but since the interior angles of a triangle must add up to `180^@`
and `/_A+/_B > 180^@`
the described configuration is not possible.
