Step-by-step explanation:
∑k=150(3k+2)
First find a1 and a50 :
a1=3(1)+2=5a20=3(50)+2=152
Then find the sum:
Sk=k(a1 + ak)2S50=50(5 + 152)2=3925

For first question, What is approximate value of "......" this part is missing so please write whose approximate value question is asking to find
For second question we have to find 
In right triangle ABC as show in attachment,
----(1)
Now AB is given by distance of point A from x axis which will be given by its y - coordinate. So 
Similarly BC is the distance of point A from y axis (horizontal distance ) and that will be given by x coordinate of A. So 
Plug these values in equation (1)

To divide fractions we flip (reciprocal ) bottom fraction and multiply it to top fraction as shown

Now 2 in top and bottom cancels out so we are left with

so thats the final answer for
