I see this triangle is isosceles. Thus, it has 2 sides of length 8 and 2 angles of measure 30 degrees.

(30 deg) + (30 deg) + (angle A) MUST add up to 180 degrees.

Thus, 60 deg + Angle A = 180 deg, so that Angle A = (180 - 60) deg, or 120 deg (answer)

Answer:

the period of this graph is 2 $\pi$

Step-by-step explanation:

The period is the length of the section that repeats. So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.

Let's look at the peaks (maximums).

One is at x = 0 and the next is at x = 2 $\pi$

2 $\pi$ - 0 = 2 $\pi$

Therefore, the period of this graph is 2 $\pi$
