Answer:
x are 42 and 138degees
Step-by-step explanation:
Given the expression sin x = 0.6691
sin x = 0.6691
Take the sin inverse of both sides
sin⁻¹(sin x) = sin⁻¹(0.6691 )
x = sin⁻¹(0.6691 )
x = 41.99
x = 42 degrees (to the nearest degree)
Since sin theta is positive in the second quadrant;
x = 180 -theta
x = 180 - 42
x = 138degrees
Hence the value of x are 42 and 138degees

Answer:
Bring like terms together Bring like terms together. All equations have two sides.
Answer:
A) y = 8.63 x
B) $224.38
Step-by-step explanation:
The the average monthly cost = (147.98+152.17+165.63)/3 = $155.26
So, For 18 employees the average monthly cost = $155.26
Let the equation that can be used to estimate y, the average monthly cost, in dollars, to buy lunch for x employees. ⇒ y = mx
For x = 18 , y = $155.26
So, m = y/x = $155.26/18 ≈ $8.63
∴ y = 8.63 x
To find the total cost for 26 employees.
∴ x = 26
∴ y = 8.63 * 26 = 224.38
The total cost of a monthly lunch for 26 employees = $224.38
