Step-by-step explanation:

value of x is 7
hope this answer helps you dear....take care!
(6,3) Is the answer________________
First, solve the area of the entire large rectangle (28)(45) = 1260
Next, find the area of the chunk that is cut out (11)(15) = 165
- we know the width is 15 because 45 - 6 - 24
Subtract the cut out piece from the overall rectangle 1260 - 165 = 1095
So hmmm recall the "inscribed angle theorem", notice the first picture
thus, check the second picture, recall, a flat line line AOD is 180° wide
