Answer:
20 dimes = 2.00
4 quarters = 1.00
Step-by-step explanation:
2.00 + 1.00 = 3.00
Answer:
5 sides
Step-by-step explanation:
The quickest way to answer this is to use the fact the exterior angles of a polygon add to 360.
If the interior angles are each 108, then the exterior angles are each 180 - 108 = 72. (using the fact that the Interior angle + exterior angle adds to 180)
Next, we just work out 360 ÷ 72 = 5.
So the polygon must have 5 angles, and therefore 5 sides.
Answer:
4a
Step-by-step explanation:
a and a =1 + 2+1= 4a
Im not that smart so im prob wrong
if i am wrong then its 3a ;(
Answer:0 3/4
Step-by-step explanation:
This is an inscribed quadrilateral. The opposite angles are supplementary. They add to 180 degrees.
angleB + angleD = 180
93 + x+30 = 180
x+123 = 180
x+123 = 180-123
x = 57
