Respuesta :
e EDF= Measure of angle DFG
Answer:
b.22.
Step-by-step explanation:
We are given that quadrilateral DEFG is a rectangle.
We know that every angle of reactangle is of 90 degrees.
We are given that
Measure of angle EDF=5x-3
Measure of angle DFG=3x+7
We know that every every angle of rectangle is equal.
Measure of angle EDF=Measure of angle DFG
[tex]5x-3=3x+7[/tex]
[tex]5x-3x-3=7[/tex]
By using subtraction property of equality
[tex]2x-3=7[/tex]
By simplification
[tex]2x=7+3[/tex]
By using subtarction property of equality
[tex]2x=10[/tex]
[tex]x=\frac{10}{2}[/tex]
By using division property of equality
[tex]x=5[/tex]
By simplification
Substitute the value x=5 then
Measure of angle EDF= [tex]5\times 5-3[/tex]
Measure of angle EDF=25-3
By simplification
Measure of angle EDF=22
Hence, the measure of angle EDF=[tex]22^{\circ}[/tex].
