Answer:
129.3 in²
Step-by-step explanation:
The shaded segment is calculated as
area of sector ABC - area of triangle ABC
area of sector = area of circle × fraction of circle
A = πr² × 
= π × 18² × 
= 324π × = 54π in²
area of Δ ABC = 
× 18 × 18 × sin60° ≈ 40.30 in²
Then
shaded area = 54π - 40.30 ≈ 129.3 in² ( to the nearest tenth )
Answer:
C. x < 40
Step-by-step explanation:
x/5 - 3 < 5
x/5 -3 + 3 < 5 + 3
x/5 < 8
(5/1) x/5 < 8 (5/1)
x < 40
Answer Is a

Answer:
See explanation
Step-by-step explanation:
The given trigonometric equation is 
.
We take the inverse cosine of both sides to get:
to the nearest degree
None of the options satisfies the given equation.
But if the question is actually;
Then;
.
.
.
.
Or
.
In this case the answer will be B
x 55
-------- = ---------
69.50 100
69.50*55= 3822.5
3822.5/100= 38.225
x=$38.22
