Step-by-step explanation:
Answer:
Pendulum will swing by an angle 0.666π
Step-by-step explanation:
We have given arc = 
And length of the pendulum l = 150 cm
Length of the pendulum will be equal to radius of the pendulum so r = 150 cm
Arc is given by 
So 

So pendulum will swing by an angle 0.666π
Sin230=sin(180+50)=sin180cos50+cos180sin50=-sin50 answer 1
90 + 3 + 4 = 97
Your answer is 97.
