Answer:
6, 8
7, 9
1, 4
they are congruent (same angle measure)
You would do tan<span>Ɵ = 9/12
tan^-1(9/12) = </span><span>Ɵ
</span><span>Ɵ = 36.87 degress
make sure your calculator is in degree mode

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
