How do I solve this?

<B = <ABC = 107°

Step-by-step explanation:

<CAB = 32° (property of isosceles triangle)

<ACB = 41° (property of isosceles triangle)

<ABC = ?

<ABC + <ACB + < CAB = 180° (sum of angles of triangle)

<ABC + 41° + 32° = 180°

<ABC + 73° = 180°

<ABC = 180° - 73°

<ABC = 107°

your answer would be 12
