Question

I need help I would really appreciate it​

Answer 1

Answer:

B

Step-by-step explanation:

Since /AOC = /BOC + /AOB, you fill in the numbers -

85 = 2x + 10 + 4x - 15

Then you combine like terms -

85 = 6x - 5

Then you add 5 to both sides -

90 = 6x

Then you divide by 6 -

15 = x

Then you substitute the x in the angles -

/BOC = 2(15) +10

/AOB = 4(15) - 15

Simplify the numbers and you get -

/BOC = 40

/AOB = 45
