Lines m and n are cut by transversal l. which angle relationships are correct? check all that apply. • <1 and <8 are alternate exterior angles.
• <4 and <6 are same side exterior angles.
• <5 and <7 are vertical angles.
• <2 and <8 are corresponding angles.
• <3 and <6 are alternate interior angles.

Correct Answer is 1 2 6

Step-by-step explanation:

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

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
