Answer:
a=-30
Step-by-step explanation:
Sine is positive while cotangent is negative. So this must mean cosine is negative since cos/sin = cot. In other words, cotangent is the ratio of cosine over sine.
Because cosine is negative and sine is positive, this places theta in quadrant 2
This is where x < 0 and y > 0. Recall that on the unit circle, x = cos(theta) and y = sin(theta).
The answer is choice B) quadrant II
56 because you gotta multiply it
Answer:
5050
Step-by-step explanation:
S=n*(n+1) / 2
S=100 * (100+1) /2 = 50 * 101 = 5050
