Can someone help me with how to do this. Please show work and don't just put the answer! Thanks

Step-by-step explanation:

Let the exterior angle be B

To find the exterior angle we must first find the value of x using one the angle property of triangles which is

the sum of any two interior angles in the triangle is equal to an exterior angle of the triangle.

To find x, add up the two given interior angles and equate to the exterior angle

We have

3x + 6 = 24 + 2x + 18

3x + 6 = 2x + 42

3x - 2x = 42 - 6

x = 36

From the question

B = (3x + 6)°

B = 3(36) + 6 = 108 + 6

We have the final answer as

Hope this helps you

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

m=-16
