The value of the 2 is 10 because it's in the tens place
You would use distribution. So, in this case, it would be 10a - 50. You use -10 to multiply -a and 5, and you get 10a, and -50.
Answer:
6 ( > ) -11
Step-by-step explanation:
6 is bigger than -11
Answer:
Options (2), (4) and (5)
Step-by-step explanation:
An angle whose measure is
terminates in quadrant 2 and its reference angle is
.
As we know only Sine value of a reference angle which terminates in 2nd quadrant is positive. Tan and Cosine of this angle are negative.
Similarly, Cosec of a reference angle terminating in 2nd quadrant is positive while sec and cot values of the same angle are negative in the 2nd quadrant.

Therefore, Options (2), (4) and (5) will be the answer.
