1. For the following coordinates, perform a 90 degree clockwise rotation. a. (1,3)
b. (-2,4)
c. (-9,-1)
d. (0,2)
e. (2,-6)

2 5/8 is the final answer! : )

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
