Question

Help me with my homework, please

Answer 1

150°

Explanation:

We know each angle in a equilateral triangle is 60° and that of a rectangle is 90° . So ,

`\implies \angle ABC = \angle DBC + \angle ABD \\\\\implies \angle ABC = 90^o + 60^o \\\\\implies \boxed{\boxed{ \angle ABC = 150^o }}`
