There are four values, including the unknown value x. The sum of the four values is the given value of the mean, 11.5, multiplied by four. Let S be the sum of the four values. Then we can write:
x = 46 + 5 = 51
The answer is: The value of x is 51.
x = 46 + 5 = 51
The answer is: The value of x is 51.
Answer:
53.52°
Step-by-step explanation:
The cosine function relates the angle to the sides shown:
Cos = Adjacent/Hypotenuse
cos(x°) = (22 ft)/(37 ft) = 22/37
The inverse cosine function is used to find the corresponding angle.
x° = arccos(22/37) ≈ 53.52°
Answer:
Step-by-step explanation:
You can use the Method of substitution.
Substitute the equation into the equation
and then you must solve for the variable x:
Apply Distributive property:
Subtract 12 from both sides of the equation and then add the like terms. Then you get:
