The complete question in the attached figure
we know that
tan R°=opposite side angle R/adjacent side angle R
opposite side angle R=72 units
adjacent side angle R=25 units
so
tan R°=72/25
R=arc tan (72/25)---------> R=70.85°-------> R=70.9°
the answer is
R=70.9°

Answer:
|CE|=2
Step-by-step explanation:
The quadrilateral is shown in the attachment
Recall that the diagonals of a rectangle are congruent.
This implies that:
|AC|=|BD|
We substitute the expressions to get:
This is now a linear equation in one variable.
Group similar terms to get:
Simplify to get:
15=3x
Divide both sides by 3 to get:
Recall again that the diagonals of a quadrilateral bisect each other.
Plug x=5
