Answer:
118
Step-by-step explanation:
Triangle CDE contains angles CDE, DCR and DER
Angles DCR=17 and DER=45 because in a kite, the diagonal on the line of symmetry bisects the angles and 34-2=17 90/2=45
The angles in a triangle add up to 180 and 180-17-45=118, meaning angle DER=118
C, because the opposite would be + 2 and none of the ions have that charge
