Geometry. i need step by step explanation on how to do each problem.

z=65

Step-by-step explanation:

11) By mid point theorem on triangles we have the sides adjacent to z and sides adjacent to 65 make a parallelogram since opposite sides are parallel.Hence angle z = 65

12)x= average of two bases (applying mid point theorem for the two adjacent triangles)

Hence x = (28+52)/2 =40

13) see attachment

The mid segment will have sides opposite as 1/2 of the corresponding diagonal

Hence ribbon required = perimeter of mid segment = 1/2(28+48)

=38 cm

14) Triangle ABC formed by joining mid points of sides of a bigger triangle would have sides as 1/2 of that of bigger triangle

Hence perimeter of ABC = 1/2 (23+12+26)

=30.5

make sure you have version 2.50

try looking in the very back of the book : )
