It’s D, E. this is because an obtuse angle is an angle that is between ninety degrees and 180 degrees. anything smaller would be an acute angle and anything larger would be a reflex angle.
hope this helps :)

if the first step of the solution of the equation 2x - 8 =5x + 3 is subtract 2x," then what should the next step be?

DaniilM [7]

The first step it to combine like terms which would be subtract 5x -2x which would be 3x

now you’re left with; -8=5x+3 now you have to subtract 3 from -8

which would be -11=5x and than you divide

hope that helps!! :)
