Answer:
10/12
Step-by-step explanation:
5 2
----- * ----- =
6 2
5 * 2 = 10
6 * 2 = 12
The fraction becomes 10/12
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
If it's complementary angles, its 45 degrees. If it's supplementary angles it's 90 degrees.
