Ineed use the information in the figure. if angle f= 116, find angle e

Ok The degrees of a triangle is always equal to 180 degrees.
The measure of angle D is equal to the measure of angle E. let the variable x = the angle of D. Because the measure of angle E is equal to the measure of angle D, let x also represent the measure of angle E. 

180=116+x+x
180=116+2x
64=2x
32=x

ANSWER 32° (don't forget units)

Ifound this on google “laws of chemical combination. it states that matter can neither be created nor destroyed. it stated that a given compound always contains exactly the same proportion of elements by weight.” i hope this you for what your looking for.
