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°
60,000 and 6,000 one is just 10 times bigger
Answer:
∠z is 79°
Step-by-step explanation:
(15, -8) :)
From C to midpoint you do (+10, -7), so you have to do that again to get to D
