Question

Help!! I don’t understand this.. whats the answer??

Answer 1

42

Explanation:

OA is perpendicular to OC, which mean it meets at 90 degrees

AOC = 90 degrees

AOB + BOC = AOC = 90

5x+8 + 6x-6 = 90

Combine like terms

11x +2 = 90

Subtract 2 from each side

11x+2-2=90-2

11x = 88

Divide each side by 11

11x/11=88/11

x =8

We want to find BOC

BOC= 6x-6

= 6*8 -6

48-6

42
