Cos = adjacent / hypotenuse
cos 25° = 4 / AB
cos 25° • AB = 4 / AB • AB
AB cos 25° ÷ cos 25° = 4 ÷ cos 25°
AB = 4/cos 25°
AB = 4.41 (nearest hundredth)
B is the answer because 12 divided by 6 is 2 and 18 divided by 6 is 3
Answer: 48/25
Step-by-step explanation:
Answer:
x + 3y + 11 = 0 is the required equation.
Step-by-step explanation:
Here the given points are A( -2,-3) and B(4,-5)
Now, slope of the equation = 
Hence, the slope of the equation is m = (-1/3)
Now, by POINT SLOPE FORMULA:
The equation of a line with slope m and point (x0, y0) is given as
(y - y0) = m (x -x0)
So, here the equation of line with (4, -5) is

or, 3y + 15 + x-4 = 0
or, x + 3y + 11 = 0
⇒ x + 3y + 11 = 0 is the required equation.
The equivalent expression is
. Option B
<h3>How to determine the expression</h3>
Given the expression
= 
Divide the multipliers, we have
= 
Let factorize the numerator in square root
= 
Eliminate the like factor in both the numerator and denominator
= 
Let's bring forth the 'x' factor, we have
= 
Thus, the equivalent expression
