Let O be the point of intersection of diagonals.
Consider triangles FOE and EOD:
FO = OD, ∠FOE = ∠EOD and OE is a common side ⇒
triangles FOE and EOD are congruent.
In congruent triangles all corresponding sides and are congruent ⇒
EF = DE = 6
Check the picture below.
as you recall from the previous exercise, x = 74°, now, using the "inscribed angle theorem" as you saw already, the green intercepted arc is 160°, so y = 160° - 74°.
as far as ∡z, well, we can just use the "inscribed quadrilateral conjecture".
4/25.Example say if it was a tatol of 25pizzas slice you would have to give 4to a friend.Cause 4is a bigger #of 2 .Like 25is a bigger number then 15!
Because every number with the decimal point have a zero infinit so it's not matter they're are same
