Answer:
If M is midpoint of AB, then
AM=MB
4x-5= 2x+11
2x=16
x=8
AM= 4x-5
=4(8)-5
=32-5
=27
BM=2x+11
=2(8)+11
=16+11
=27
Hope it helps:-)
I guess that u = μ & that a=σ. If so:
μ =100 & that σ =20 & x=20
Z score = (x-μ) / σ ==> Z score = (90-100)/20 ==> Z = - 0.5
Since the ratio of sides is 4 to 3, the proportion is:
x =
9
AB^2 + BC^2 = AC^2
AB^2 + 6^2 = square root 117^2
AB^2 + 36 = 117
Now subtract 117 from both sides
AB^2 = 81
AB = square root 81 = 9
Therefore AB is 9 cms.
