hey yall im confused for number 4 i put given but my teacher said correct 4 mark what you know so you can know what postulate to use .can someone explain.(i will mark you as the branlest wtv)

Step-by-step explanation:

3) LN≅ LN               Reflexive property

4) ΔONL ≅ΔMLN    Given

5) LM ≅ NO              CPCT - Corresponding parts of congruent triangles

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
