Answer:

(a)x=25 (b)x=51

Explanation:

Look at the first diagram, the arc that corresponds to 25 is congruent to arc that corresponds to x, so x=25.

Look at the second diagram, the arc that corresponds to angle ACB is 2cm and the arc that corresponds to x is 6cm which is three times the first arc, so the angle is also three times of angle ACB. So x=3*17=51
