Question

Help me please! Would be greatly appreciated! :)

Answer 1

MR=20

Explanation:

These appear to be isosceles triangles, so their bases are equal on both sides. For the little triangle in the center, one side is 6, so the other will also be 6. Now the larger one has MN=4, so QR=4 as well.

6+6+4+4=20.
