It would be the first graph
Well there is no picture but I think your answer should be <span><span>38/360 </span>∗100π </span>expressed as a decimal number..
D: 28.97 ft squared I believe is the answer
Step-by-step explanation:
Note that since 
we can see from the figure that 
and 
have the same measure.
a) To solve for the length of 
we write
b) Since the two triangles are congruent, we can say that 
so we can write
Solving for y, we get
Answer:
(a) 78
Step-by-step explanation:
The sum of arcs of a circle is 360°. The measure of θ is the average of the measures of arcs BD and AC.
AC +AD +BD +100 = 360
(2BD) +(2BD) + BD = 260 . . . . use the given relation for AC, AD; subtract 100
BD = 52 . . . . . . . . . . . . . . . . . divide by 5
θ = (AC +BD)/2 = (2(52) +52)/2 = 52 +26
θ = 78 . . . . degrees
