Leah and Dan are trying to prove that the triangles below are congruent. Leah says they are congruent by the AAS congruence criteria, while Dan says they are congruent by the ASA congruence criteria. Who is correct? Explain.

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

it is 10.6 according to my calculations
