here the answer is 10=a
= tan 2a = cot(a+60°)
= cot(90-2a) = cot (a+60°)
= 90°-2a = a+60°
= 90°-60° =a+2a
= 30 = 3a
= 30\3 = a
= 10 = a
hope it you and plz mark as brainliest..☺
we are given the following arithematic sequence and we are to find the 10th term in this sequence:
where is the number of the term.
to find the 10th term, we will simply substitute '10' in place of n in the above given formula:
therefore, the 10th term of this sequence is 330.
