Highly appreciated if someone me with this question

C

Step-by-step explanation:

B and D are equal. You could call their sum = 2x

a = 25 degrees (Vertically Opposite Angles)

C = 95 degrees. (Vertically Opposite Angles)

The total is 360 degrees. So let's add everything up and see what we get.

a+b+c + 25 + d + 95 = 360 degrees.      Substitute for the known letters.

25 + x + 95 + 25 + x + 95 = 360             Combine like terms on the left

50 + 2x + 95 + 95  = 360                        Combine numbers on the left

240 + 2x = 360                                        Subtract 240 on both sides

240 - 240 + 2x = 360 - 240                    Combine

2x = 120                                                    Divide by 2

x = 60

b = 60

a = 25

a + b =60 + 25 = 85
