Answer:
1. C 2. B
Step-by-step explanation:
1. find the total circumference, d times pi, then put 42 over 360 and multiply them to get that section
2. The actual value of x is 33.2
So I plugged in that value for all of them
9 times 21 is 189
the answer is 189 inches

Answer:
x = 118 degrees approximately
Step-by-step explanation:
Here, we want to get the measure of the angle marked x
We shall use the side facing it and apply the cosine rule
The side facing the angle measures 90
Thus, we have it that;
90^2 = 55^2 + 50^2 - 2(50)(55) cos X
2575 = - -5,500 cos X
X = cos^-1(-2575/5,500)
X = 118 degrees approximately
