Answer:
√3
Step-by-step explanation:
cot²(θ) = csc²(θ) -1 . . . . . a relevant identity
= 1/sin²(θ) -1
= (1/(1/2))² -1 = 2² -1 = 3
Then ...
cot(θ) = √3 . . . . . . . . take the square root
Answer:
17
Step-by-step explanation:
I am pretty sure it is B.
Answer: C
Step-by-step explanation: The answer is C because x is equivalent to 10 in both problems. X is equal to 10 in the problem 2x + 7 =27 because 2 x 10 = 20 + 7 = 27. X is also equal to 10 in the problem 5x - 15 = 35 because 5 x 10 = 50 - 15 = 35. This means the answer is C.
