Step-by-step explanation:
Answer:
The answer to your question is x = 66.42° and x = 293.6°
Step-by-step explanation:
Data
cos x = 2/5
x = ?
Process
1.- Look at the sign of 2/5.
2/5 is positive so the angle we are looking for is in the first or the fourth quadrant.
2.- Remember the side that the trigonometric function relates
cos x = Adjacent side / hypotenuse
then, adjacent side = 2
hypotenuse = 5
3.- Get cos⁻¹ x
cos⁻¹x = x = 66.42°
4.- If the angle is in the first quadrant x = 66.42°
5.- If the angle is in the fourth quadrant x = 293.6°
Answer:
6p -8
Step-by-step explanation:
The three sides of an equilateral triangle are all the same length. (This is the literal meaning of "equilateral.") So, the length of one side is 1/3 the total length.
each side = ![\dfrac{18p-24}{3}=\dfrac{18p}{3}-\dfrac{24}{3}=6p-8](https://tex.z-dn.net/?f=%5Cdfrac%7B18p-24%7D%7B3%7D%3D%5Cdfrac%7B18p%7D%7B3%7D-%5Cdfrac%7B24%7D%7B3%7D%3D6p-8)
