Sin2x = 2 sinx cosx
so 12 sinx cosx = 6 sin2x Answer
The total of the internal angles in a tetradecagon is 2160.
2160 - 2012 = 148
The remaining angle must be 148 degrees.
bearing in mind that 1 yard = 0.914 meters, so therefore 27 meters is then 27/0.914 yards and 18 meters is 18/0.914 yards

Answer:
1: 75
Step-by-step explanation:
20cm : 15m
Convert meters to cm
1 meter = 100 cm
15m = 15 x 100 = 1500 cm
20cm:1500cm
Divide both sides of the ratio by 20
=> 1 : 1500/20 = 1: 75
