Is it (6-x) all over x, or 6- (x/3) ?
Answer:
F. 1.978 > 18979
Step-by-step explanation:
For this the easiest way is to picture the situation. You will notice that you have right triangle in front of you. Length of ladder is you largest side of triangle. Right angle is oposite from it. That means we can use simple trigonometric functions.
Because of the angle we need it is easiest to use cosine function
cos(x) =
cos(x) = 4/7
x = arccos(4/7) = 55.15 degrees
Answer is C
Answer:
x = -2
Step-by-step explanation:
The segments described in the question are equidistant (meaning they are the same length). Therefore, using algebraic techniques, we can set these two equal to each other and solve for x.
4x - 8 = 6x - 4 Combine like terms by subtracting 6x from both sides.
-2x - 8 = -4 Combine like terms by adding 8 to both sides.
-2x = 4 Divide by -2 on both sides of the equation.
x = -2
