Answer:
Say that the shape is a parallelogram with equal length sides;
AB = CD
ABD = CDB as the bisecting lines (you have drawn) prove ABD : CDB are both isosceles triangles.
Therefore ABD = ADB
Draw the shape's diagonals as each others' perpendicular bisectors;
Draw the shape's diagonals bisect both pairs of opposite angles.
If two non congruent angles were given in example 70 degree and 110 degree then say M ∴ = (1/2 )(M∴BAD) = 35 = (1/2 )(M∴BEF) = 35
and do the same for 1/2(M∴ABC) = 55 = 1/2 (M∴CDA) = 55
3s = 72 (Multiply 8 both side).
s = 24 (divide by 3 both side)

Answer:
f(x) = x - 3
Step-by-step explanation:
note that y = f(x) , then
x - y = 3 ( add y to both sides )
x = 3 + y ( subtract 3 from both sides )
x - 3 = y , that is
f(x) = x - 3
Answer:
Step-by-step explanation:
The smallest is 4 and since there has to be two fives, the two middle numbers are 5. The range 3 so that means the biggest number is 7. So the set is 4,5,5,7
