Answer:
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
