Need help with this problem

Step-by-step explanation:

In this problem, it is given that lines (AO) and (OC) are perpendicular. This means that when the lines intersect, the four angles formed each have a measure of (90) degrees. As per the given diagram, angles (<AOR) and (<ROC) add up to make (<AOC). Thus, one can form the following equation and solve for (x).

Substitute,

Simplify,

Inverse operations,

Substitute this into the equation for the measure of angle (<BOC) to find the numerical angle measure:

i think the amount would be $140.62
