98 points and will mark brainliest given the equation of the line y=-x-2. what is the equation of the image after a 270 degree rotation about the orgin. name the relationship (parrell, perpendicular, neither) 98 points and will mark brainliest

2/4 of 360 , Perpendicular

Step-by-step explanation:

(Took the test and got this right)

If my answer qualifies please mark brainliest!

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
