Answer:
Option (D)
Step-by-step explanation:
In the given triangle ABC,
Sum of all interior angles = 180°
m∠A + m∠B + m∠C = 180°
72° + 85° + m∠C = 180°
m∠C = 180 - 157
m∠C = 23°
By applying Sine rule in the triangle,
a = = 15.09
b =
b = 15.81
Therefore, option (D) will be the answer.
Answer:
4n+2
Step-by-step explanation:
The common difference between the terms is 4 which means that the sequence is an arithmetic sequence.
The general formula for arithmetic sequence is:
where a_n is the nth term, a_0 is the first term and d is the common difference between them.
We know that
Putting the value in general formula:
So the generalized pattern is 4n+2 ..
