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.
 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
, since angle is in radian
Now convert radian into degree by using following formula,

So multiplying  with
 with  to convert it into degree.
 to convert it into degree.

Simplifying,

So to nearest tenth,

Answer:
A and D
Step-by-step explanation:
One side-base right triangle and one angle-based right triangle.
 
        
                    
             
        
        
        
An obtuse triangle has one obtuse angle, or an angle that measures more than 90° but less than 180°. Options 1 and 2 are not correct, because these are acute angles.
So, one of the angles must be 40°, and the other may be 100° or 120°.
The measures of the angles in a triangle add up to 180°.

The other two angles are 40° and 100°.
