Formula to determine the scale factor,
Scale factor =
2 =
2 =
P'Q' = 4 cm
Similarly, for the length of A'B',
2 =
2 =
A'B' = 3 cm
For the length of M'N',
2 =
2 =
M'N' = 6 cm

Step-by-step explanation:
I didn't need the other angles, but right of the bat you can tell it's two right triangles back to back.
<em>y </em> has to be 90° , as you have noticed they already gave you 70° on the right side of the shape meaning if you were to add 90 which is why plus 70 what would that give you? 160.
the total interior for a triangles angles has to be 180°. if you do the math 180 - 160 you get the leftover 20° for x.
I suck at explaining stuff, hope this helps
The answer must be 
since the triangular pyramid has 4 faces and each has an area of 30 
we should multiply that by 4 , so :
