Step-by-step explanation:
m< AOC = 90°
m< AOB +m<BOC = 90°
6x-12+3x +30 = 90°
9x +18° = 90°
9x = 90- 18° = 72°
x = 8°
m<AOB =6(8)-12 = 48-12 = 36°
You must get a common denominator of 100. Transfer 594 7/25 to 14857/25 by multiplying 594 by 25. Then multiple 25 and the numerator by 4. For your answer of 59428/100. Then add 59428/100 + 8937/100 for the answer of 68365 then divide it by 100. overall answer should be 683.65. hope this helps
No because if that happened they wouldn’t be able to do it again so yeah
