Question

∆DFE=14° EF=DE угол E=?

Answer 1

Ответ:

1. т.к. треугольник DFE- равнобедренный по условию, то угол E= (180°-14°):2= 81°

Объяснение:

свойство равнобедренного треугольника- углы при основании равны, то угол Е и угол D равны.

Answer 2

To find the angle E, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

In triangle DEF, we know that angle DFE is 14 degrees and angle EFD is 180 - 14 = 166 degrees (since the sum of angles DFE and EFD is 180 degrees).

Now, we can consider triangle EDF. We know that angle EDF is 166 degrees and angle DEF is 180 degrees (since the sum of angles EDF and DEF is 180 degrees).

To find angle E, we subtract the sum of angles EDF and DEF from 180 degrees:

Angle E = 180 - 166 - 180 = -166 degrees

However, angles are typically measured from 0 to 180 degrees (or 0 to 360 degrees in a full circle). Since the value of -166 degrees is outside this range, it doesn't make sense in the context of a triangle.

Please double-check the information given, as there may be an error or missing information in the problem statement.
