Answer:
second and last one
Step-by-step explanation:
the less a negative the closer it is to zero which means it's closer to being a positive
Answer:
Measure of minor angle JOG is 
Step-by-step explanation:
Consider a circular track of radius 120 yards. Assume that Cherie starts from point J and runs 200 yards up to point G.
.
Now the measure of minor arc is same as measure of central angle. Therefore minor angle is the central angle
.
To calculate the central angle, use the arc length formula as follows.
Where
is measured in radian.
Substituting the value,
Dividing both side by 120,
Reducing the fraction into lowest form by dividing numerator and denominator by 40.
Therefore value of central angle is
, since angle is in radian
Now convert radian into degree by using following formula,

So multiplying
with
to convert it into degree.

Simplifying,

So to nearest tenth, 
Answer:
speeds above 343 m/s
Step-by-step explanation:
the faster you go the faster the supersonic
Since the three angles of a triangle add to give 180°
The the size of the largest angle 4 = 180° ×

= 180° ×
∴ the size of the largest angle = 80°
