I need a little bit more detail in order to answer your question properly
1% of 19,500= 195
6% = 1%x6 = 195x6 = 1170
19500+1170=20670
Answer:
x = 40
Step-by-step explanation:
Using similarity theorem, we have the following:

Solve for x

Cross multiply


Subtract 24x from each side


Divide both sides by -15
40 = x
x = 40
Answer:
Option D
∠GDE is supplementary to ∠DEF and also supplementary to ∠FGD
Step-by-step explanation:
To use the supplementary property to identify a parallelogram. The condition must be that that the same-side interior angles (consecutive angles) are supplementary.
Thus for parallelogram DEFG
D --------------------E
/ /
G---------------------F
Thus, we have it that the condition that is most sufficient to show that quadrilateral DEFG is a parallelogram is
∠GDE is supplementary to both ∠DEF and ∠FGD
Cos(Angle) = Adjacent leg / Hypotenuse
Cos(X) = 3.5/4.6
X = arccos(3.5/4.6)
X = 40.46 degrees.
