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
Answer:
18
Step-by-step explanation:
Answer:
8/15
Step-by-step explanation:
To divide by a fraction, change the division to a multiplication, and flip the fraction.
2/5 / 3/4 = 2/5 * 4/3 = 8/15
Two triangles are Similar if the only difference is size (and possibly the need to turn or flip one around). Therefore would be answer B.
Find the ratio
The distance would be 480 ft
Answer:
Then maybe pay attention in class and know what to do and not ask strangers for help. We answer to try and help. Not like we get paid. We literally are just trying to help
