Answer:
∠A = 120°
∠B = 60°
Step-by-step explanation:
Since, ∠A and ∠B form a linear pair.
Therefore,
∠A + ∠B = 180°.....(1)
It is given that:
∠A = 2∠B..... (2)
From equations (1) & (2)
2∠B + ∠B = 180°
3∠B = 180°
∠B = 180°/3
∠B = 60°
So, ∠A = 2∠B = 2*60°
∠A = 120°
The "vanilla" y=cos(x) function oscillates between -1 and +1. In the given function, only a multiplication with 3 is applied. The min and max scale accordingly, so the maximum becomes +3 and the minimum -3.
The x interval of <span>[-2π, 2π] ensures that all y values are enclosed; the cosine makes two full sweeps.</span>
