Answer:
88
Step-by-step explanation:
First you must find the circumference of the entire circle and to do this you use 2πr. The radius in this case is PX=15. This means that the circumference is 30π. Now to find the arc length, we know that the measure of arc XY is 23 degrees, and since there are 360 total degrees in a circle, we must subtract 23 from 360 to get 337° as the measure of arc XQY. Now we have to find what portion of the circumference of the circle is in this arc, and to do this you divide the arc length (337°) by 360° and multiply by the circumference of the circle. Doing this would get you which equals ~28. Finally, you have to multiply this by the value of pi and get approximately 88, which is your answer.
ANSWER
111.3 square units.
EXPLANATION
The formula for calculating the area of a triangle is.
Let us the side of the triangle with side 12 units to be the base of the triangle.
Then the height of the triangle can be determined from the diagram using trigonometry.
We now plug in the values in to the formula to obtain,
