I think it’s 3 because it’s just how I think it is I’m probably not correct but I think it’s 3
Answer:
x = 0, π/4, π, 7π/4
Step-by-step explanation:
sin(2x) = √2 sin x
Use double angle formula.
2 sin x cos x = √2 sin x
Move everything to one side.
2 sin x cos x − √2 sin x = 0
Factor.
sin x (2 cos x − √2) = 0
Solve.
sin x = 0, cos x = ½√2
x = 0, π/4, π, 7π/4
Question 1: 4/25 = 0.16
Question 2: 4 6/25 = 106/25 = 4 6/25 = 4.24
Question 3: 7.8 = 7 8/10 = 7 4/5
hope this helps
