Step-by-step explanation:
In this problem, one is asked to find the measure of the arc in degrees. This problem provides one with a diagram since the center is unnamed, call the center point (O). One is given the information that angle (<DOE) has a measure of (90) degrees. One is asked to find the degree measure of the surrounding arc (DE).
The central angles theorem states that if an angle has its vertex on the center of a circle, the degree measure of the angle is equal to the degree measure of the surrounding arc. One can apply this here by stating the following:

For 175 : 250 divide them both by 25 to get 
< 
25 goes into 175 > 7 times > 25 into 250 is 10 times! >
For the second one 16 : 40 just divide the top and bottom by 8 since 8 is a common factor of both which will give us
.
8 goes into 16, 2 times and 40, 5 times.
