Ellen is drawing two polygons. one of tue polygons has 3 more angles than the other. what shapes could she be drawing?

Pentagon and an OCTAGON

Step-by-step explanation:

Polygons are are plane figures with three or more sides. Since plane figures with 3sides are triangles and those with 4sides are quadrilaterals, I will take a plane figure of 5sides as one of the two polygons Ellen is drawing

A plane figure with 5sides and 5angles is a PENTAGON

If one of the polygons has 3 more angles than the other, then the other polygon she is drawing was a polygon with (5+3) i.e 8sides and 8angles. This polygon is known as an OCTAGON

Based on the conclusion, the shape Ellen could be drawing is a PENTAGON and an OCTAGON

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
