900 : 1
The linear ratio = a : 30a = 1 : 30
volume ratio = 1³ : 30³ = 1 : 900
ratio of larger to smaller = 900 : 1
Answer: D
Step-by-step explanation: 
Answer:
50
Step-by-step explanation:
The angle is on the right side therefore the arrow is pointed at 180 and the other is pointed at 130. So to get the difference you need to subtract the greater number from the smaller (180-130)=50
Answer: x = 15, 95 degress, 85 degrees
Step-by-step explanation:
(2x + 65) + (3x+40) = 180
5x +105 = 180
5x = 75
x = 15
2 (15) +65 = 95 deg
3 (15) +40 = 85 deg
