Answer:
13.86 ft
Step-by-step explanation:
This can be represented by a right angled triangle with a hypotenuse of 16 feet and an angle of 60° between the hypotenuse side and the adjacent side.
The height of the pole is the side opposite to the angle 60°.
The trigonometric function states that for a right angled triangle:
sinθ = opposite / hypotenuse, cosθ = adjacent / hypotenuse, tanθ = opposite/ adjacent
To find the height of the flagpole, we use:
sin(60) = height / 16
height = 16 * sin(60)
height = 13.86 ft
The person with the incorrect reasoning for the height of the flagpole is Charlie when he should have utilized the sin function. Because he incorrectly selected the function.
Answer:
Step-by-step explanation:
Based off the typical rules of integers, expressions like these can be simplified to look different but mean the same thing.
In this case, we subtracted a negative value from a positive value; by doing this, we actually added positive 4.
Based on the same principals, adding a negative number is equivalent to subtraction!
Any time you see equations similar to this, you want to cancel out the 2 negative signs to make it positive!
