Answer:
Step-by-step explanation:
Since we use the sides opposite and adjacent to the given angle, we will use the tangent ratio:
Insert the given values:
Since we need to find the angle, use the inverse:
Insert the equation into a calculator:
Round to the nearest tenth:

Answer: 16
Step-by-step explanation:
Let F(x) = x^2 + 2x -8
Adding 1 and - 1 at equation
F(x) = x^2 + 2x + 1 - 1 -8
Rewrinting the first 1 = 1^2
F(x) = x^2 + 2x + 1^2 - 1 - 8
Now look:
x^2 + 2x + 1^2 = ( x + 1)^2
Then,
F(x) = (x + 1)^2 -1 -8
F(x) = (x + 1)^2 -9
This is the answer !
If us to want.
(x + 1)^2 -9 = ( x+1)^2 - 3^2
= ( x+ 1 -3).(x +1 +3)
= ( x - 2).(x +4)
Answer:
1/4
Step-by-step explanation:
multiply the whole number to the denominator
so 4(2) = 8
u now have 2/8
simplify the fraction and ur done :)
in decimal form .25
