The group of those shapes are parallelograms
Is this <ABD?
if so, all lines tangent to a circle, its point of tangency is perpendicular to the center of the circle. So <ABD = 90 degrees
The GCF is going to be 13, sorry your answer is late
The coefficient would be 5. a would be the variable, + would be the operator, and 2 would be the constant. Hope I helped!!!!!
