The point P(x, y) lies on the terminal side of an angle 0 = –60° in standard position. What are the signs of the values of x and y?

X is positive

Y is negative

Step-by-step explanation:

Just take the cos of angle - 60 for X

and also take the sin of angle - 60 for Y

You will find x positive, and y negative

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
