For this case we have:
"One number plus its double equals its half plus fifteen, what is the number?"
x: Let the variable that represents the unknown number
According to the statement we have:
"One number plus its double" is represented as:
"Its half plus fifteen" is represented as:
Then we have the following expression:
We solve the equation:
So the number is 6
Answer:
Tangent is the ratio opposite/adjacent
tan(angle) = opposite/adjacent
tan(x) = 8/5
tan(x) = 1.6
x = arctan(1.6)
x = 57.9946
x = 58 degrees which is the answer
The answer is approximate to the nearest whole number. Make sure your calculator is in degree mode.
