Answer:
64.62°
Step-by-step explanation:
Use good 'ol SOHCAHTOA. Since we know the hypotenuse and the adjacent values, we use cosine.
Therefore:
Take the inverse cosine of each side:
Inverse cosine of cosine cancel each other out:
Use a calculator:
Therefore the angle is 64.62°
An equation is formed of two equal expressions. The given equation is not true.
<h3>What is an equation?</h3>An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The complete question is: Check whether the given equation is true or not?cos2pi/7+cos4pi/7+cos8pi/7=1/8.
To know if the given equation, is true or not, both the sides of the equation are needed to be solved separately.
The value of when simplified is equal to -0.5, or the value can be written as -(1/2).
Since the right side of the equation is equal to -1/2, while the right side of the equation is 1/8. Thus, the given equation is not true.
Hence, the given equation is not true.
