Answer:
36
Step-by-step explanation:
AOB + BOC = AOC
AOC = 90 since the lines are perpendicular
6x-12 + 3x+30 = 90
Combine like terms
9x + 18 = 90
Subtract 18 from each side
9x+18-18 = 90-18
9x = 72
divide by 9
9x/9 = 72/9
x = 8
AOB = 6x - 12
= 6*8 - 12
= 48 -12
= 36
Answer:
AOB = 36
Step-by-step explanation:
OA is perpendicular to OC
AOB + BOC = 90 ------------equation
where:
AOB = 6x - 12
BOC = 3x + 30
plugin values into the eq.
6x - 12 + 3x + 30 = 90
6x + 3x + 30 - 12 = 90
9x + 18 = 90
9x = 90 - 18
9x = 72
x = 72/9
x = 8
plugin values to <u>AOB = 6x - 12</u>
AOB = 6x - 12
AOB = 6(8) - 12
AOB = 36
