Question

I need to know if A and B are correct and I need HELP WITH C

Answer 1

Given:-

A triangle.

To find the angles.

So now we use the formula that the sum of angles in the triangle is 180 degree.

So we get,

$\begin{gathered} 24+x+x=180 \\ 24+2x=180 \\ 2x=180-24 \\ 2x=156 \\ x=\frac{156}{2}=78 \end{gathered}$

So the required value of x is 78.
