Answer:
60°
Step-by-step explanation:
We'll begin by calculating EC. This can be obtained as follow:
Angle EAC = 39°
Hypothenus = EA = 3.7 m
Opposite = EC =?
Sine EAC = Opposite /Hypothenus
Sine 39 = EC / 3.7
Cross multiply
EC = 3.7 × Sine 39
EC = 2.3 m
Finally, we shall determine angle BEC. This can be obtained as follow:
Adjacent = EC = 2.3 m
Hypothenus = BC = 4.6 m
Angle BEC =?
Cos BEC = Adjacent / Hypothenus
Cos BEC = 2.3 / 4.6
Cos BEC = 0.5
Take the inverse of Cos
BEC = Cos¯¹ 0.5
BEC = 60°
Thus, angle BEC is 60°

Answer:
and 
Step-by-step explanation:
The correct equation is:

To solve by completing the square method.
Solution:
We have:

In order to solve by completing the square method we will carry out the following operations to the given equation to get a perfect square binomial.
We can write as:

[As
]
Adding both sides by 

Taking LCD to add fraction.


Taking square root both sides.


Subtracting both sides by
:


So, we have:

Answer:
2 benches
Step-by-step explanation:
Selling Price per bench = $175
Cost per bench = $100
profit per bench = $175 - $100 = $75
assuming that he sell x benches a month,
profit in 1 month = $75x
given that his advertising costs are $150 per month, in order to break even, his profit must be equal to his advertising profit.
i.e
$75x = $150
x = 150/75
x = 2
32 is the outlier, cause it’s much bigger than the other numbers
