Answer:

Angle BOC = 28; Angle AOB = 21

Step-by-step explanation:

Because angle AOC = AOB + BOC you can set the equation:

2x+10 + 4x-15 = 49

<solve for x>

6x - 5 = 49

6x = 54

x= 9

<plug in x for the angles>

BOC = 2(9) +10 = 28

AOB = 4(9) - 15 = 21

First you multiply both sides by 10, add 40, divide by 4, then square root

10*(4x^2-40/10)= (36)*10
(4x^2-40)+40=(360)+40
(4x^2)/4=(400)/4
x^2=100
x=10
