18 plus 12 divided by 2 = thats how u get the answer
3d is the answer if I am wrong please let me know
The inside angles of a triangle need to equal 180 degrees
in this triangle the lines NP and OP are identical so the 2 unknown angles would be equal
so the 2 unknown angles would be 180 - 112 = 68 / 2 = 34 each
angle N & O are 34 degrees
The distance between points A and B
(-1/8)-(-6/8) = 5/8
