kriti walks 15m towards West and then 10m to her left. now every time turning to her right , she walks 20m , 25m and 35m respectively . How far is she now from her starting point

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

- (2, -7)

- lines r and s and lines t and u must be parallel

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
