so your answer should be 9.
-2 sqrt (20) -sqrt(125)
-2 sqrt(4*5) - sqrt(25*5)
-2 sqrt(4)sqrt(5) -sqrt(25)sqrt(5)
-2 *2*sqrt(5) -5sqrt(5)
-4sqrt(5) -5sqrt(5)

Answer:
(i) 120°
Step-by-step explanation:
(i)
sine 90 = 1
sine 120 = 0.87 (rounded up to two decimal places)
sine 150 = 0.5
sine 180 = 0
sine 210 = -0.5
sine 240 = -0.87 (rounded up to two decimal places)
sine 270 = -1
sine 60 = 0.87 (rounded up to two decimal places)
So the angle x such that 90° < x < 270° that has the same sine value as 60° is 120°
