From the given picture, it can be seen that the radius of the circle = 16 units
Also, the measure of central angle XYZ 
radians
The area of sector with radius r and angle x radian is given by :-
Now, the area of the shaded sector is given by :-
Answer:
The vertex is (-1, 4)
Not sure what the table looks like, but just plug the x values into the equation to get a complete point
Graph the points on a graph
Step-by-step explanation:
Answer:
86
Step-by-step explanation:
Difference means subtraction so you do 136-50 ：）
All triangles have a total of 180° in them.
So to find x, simply take 50° and 100° from 180°:
x = 180 - 100 - 50
= 30°
So x = 30°, and thus option D
