THat's the picture that goes along with this equation how would i solve it because i can't solve it and put there equal and i can't put they equal 180 please help!
In triangles MEF and MDF, you have two pairs of equal sides, but the angles included between those sides are UNEQUAL. You should have a theorem that says "If two triangles have a pair of equal sides, but the included angles are unequal, then the sides opposite the unequal angles are also unequal in the same order."
Since <1 > <2, the side of triangle MDF which is opposite <1 must be greater than the side of triangle MEF which is opposite <2.
Or,
DF > EF
Now....you are GIVEN expressions for the lengths DF and EF. Substitute those expressions in the above inequality, and solve for the possible values of x.
