I am having trouble with this

x=16

Step-by-step explanation:

If the triangles are similar then their sides are in proportion.

Set the proportions 20/(3x+8)=(x-1)/(x-1+27)

solve for x,

cross multiply

20(x+26)=(x-1)(3x+8),

distribute

20x+520= 3x² +8x-3x-8,

combine like terms

3x²-15x-528=0

solve using quadratic formula

x=16 and x= -11 reject because we cannot have negative measurements

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
