In rectangle ABCD, the diagonals intersect at point
E. Find the value of x and y
if BE = 3x + 1, ED = x +7
and EC = 5y.

d

step-by-step explanation:

d

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
