Question

Angela drew 9 rhombuses and 6 trapezoids. She wants to find q, the total number of angles in her quadrilaterals. Explain how Angela can find q.
Plz help me this.

Answer 1

I'm pretty sure it's
q= 4(9)+4(6)
This is true, since both are quadrilaterals, so they have 4 sides and therefore 4 angles. There are 9 rhombuses, so each has 4 angles. This would mean you'd have to multiply each quadrilateral by 4 to find your answer. 
I hope this helps a little.
