Answer:
96 * 144 - 168 * 42
Step-by-step explanation:
So the area of the wall is 96 * 144
And the area of the tiled part is 168 * 42
So it would be 96 * 144 - 168 * 42
Order pair are the two point on xy directio and sheaded are means area below the line
Arc DB = 2 ( angle DAB ) = 2 (35) = 70 degrees
Arc DG = 2 (Arc DB) = 2 (150) =150 degrees
Arc DAG = 360 - Arc DG = 360 - 150 = 210 degrees
Angle DCG = (210 - 150) /2 = 30 degrees
Angle DCB = 30/2 = 15 degrees<span />
