Can someone help me out with this problem

We have to decide which expression is greater than the other.

18 ÷ 6 + 3 is our first expression. To solve, we go from left to right, solving with division first.

Then, we can add 3 to 3.

6 + 12 + 3 is our next expression. To solve, we go from left to right, solving with addition.

Since 6 is less than, we replace the ? with <, which is the less than symbol.

To help you remember: < can stand for the “L” in “Less than.”

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
