Question

Help me with this Geometry question please

Answer 1

Answer:

b=2b-53  :  b=53. Then SU=53

Step-by-step explanation:

Solution

b=2b-53  :  b=53

Steps

If QU=b and SU=2b-53

That mean b=2b-53 because QU=SU

Substract 2b from both sides

b-2b=éb-53-2b

Simplify

-b=-53

Divide both sides by -1

-b/-1=-53/-1

Simplify

B=53

NOTE :  

Theorem 1: In a parallelogram, the opposite sides are of equal length. Theorem 2: If the opposite sides in a quadrilateral are the same length, then the figure is a parallelogram. Theorem 3: A quadrilateral is a parallelogram if and only if the diagonals bisect each other
