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
