An isosceles triangle has a vertex angle of 100 degree what are the other angles?

The other angle measures are 40 and 40 degrees respectively.

Step-by-step explanation:

100 + 2x = 180

=> 2x = 80

=> x = 40

Since it is isosceles, the two remaining sides are equal, and therefore, they will have equal angles of 40 degrees.

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
