Help me solve please

Step-by-step explanation:

The addition of angles ABD and DBC make up the larger angle ABC. We know that angle ABD = 65 and DBC = 60, therefore

angle ABC = 65 + 60 and

angle ABC = 125 degrees

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
