step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

d will be the best answer

answer: the answer to this problem is 2x and 2-x both have x as well as 2

step-by-step explanation: first you have to see what is the closest thing they have similar second you note it example 4x and 4+x they both have x and 4
