Step-by-step explanation:
"Root 9.8" means the square root of 9.8, 
.
Since we are being asked to find it on the number line, I am guessing they want us to estimate. We know that the square root of 9, 
, is equal to 3. Since 9.8 is slightly bigger than 9, the square root of 9.8 will be a little bit over 3.
<em>Want to confirm? Using a calculator for the square root of 9.8 gives us 3.13.</em>

Answer:
The angle is of 600º.
Step-by-step explanation:
Angle of -60:
An anle of -60 is the same as an angle of -60 + 360 = 300º, which is in the fourth quadrant. In the fourth quadrant, just like in the third, the sine is negative.
Equivalent of an angle of 300º in the third quadrant:
The equivalent of an angle of 300º in the third quadrant(between 180 and 270) is given by: 270 - (300 - 270) = 270 - 30 = 240º. That is, they have the same sine.
Angle between 450 and 630:
This is on the second lap of the trigonometric circle, that is, we take the original measures and add 360º(length of a lap). So
240 + 360 = 600º
The angle is of 600º.
