Question

A trapezium with parallel sides of length as 7 : 3 is cut from a rectangle 30dm by 4 dm so as to have an area of one-third the latter find the length of the parallel sides
for 100 points answer must be 14 and 6
answer must be in clear method​

Answer 1

Step-by-step explanation:

Given , sec−11+x2+cosec−1(y1+y2)+cot−1(z1)=π

⇒tan−1x+tan−1y+tan−1z=π

⇒tan−1(1−xy−yz−zxx+y+z−xyz)=π=tan−1(0)

⇒x+y+z−xyz=0

⇒x+y+z=xyz
