Question

Please show your work and I need this in 10 minutes

Answer 1

Because of two sides $AC$ and $BC$ are equal, the angles $\angle A$ and $\angle B$ are also equal. We know that sum of angles of the triangle is equal $180^{\circ}$. Let $x$ represent $\angle B$. So, to find $\angle B$ we need to solve the equation:
$2x+50=180$
$2x=180-50$
$2x=130$
$x=130/2=65$

The answer is: $\angle B = 65^\circ$

Answer 2

The answer is 65 degrees because there are 180 degrees in a triangle and the triangle isosceles and 130 (because 50 degrees minus 180 = 130) divided by 2 is 65.  Youre welcome
