How would i do this? ? will give brainiest

x = 70°

Step-by-step explanation:

I will assume solving the problem where 2 parallel lines are cut by a transversal that has an angle 110 and another angle x. Lets solve for x.

When 2 parallel lines are cut by transversals, we have 4 pair of equal angles.

Now, looking at the figure,

The angle beside (adjacent) to the angle 110 is same as the angle x degrees.

These are corresponding angles, which are equal.

So, we have 110 degree angle and x degree angle adjacent to each other in a straight line. This is a straight angle.

A straight line (or, straight angle) creates 180 degrees. Thus, we can write:

110 + x = 180

Now, we solve for x:

So,

x = 70°

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
