Group Title
The figure below shows CB = 8, BE = 12, AB = 3x – 1, and DB = 4x + 2.
Triangle ABC is a right triangle with measure of angle ACB equal to 90 degrees. The measure of side CB is 8 and AB is 3 multiplied by x minus 1. D is a point on the left of C on BC extended. A point E is labeled on AB such that DE is perpendicular to AB. Measure of EB is 12 and DB is 4 multiplied by x plus 2
If △ABC ~ △DBE, the value of x is _________

8/12 is 2/3 2/3 = (3*x1)/(4*x+2) With me so far?

irishchelsc Group TitleBest ResponseYou've already chosen the best response.1
okay. so simplify the ratio

timo86m Group TitleBest ResponseYou've already chosen the best response.1
Yup :) 8/12=(3x1)/(4x+2) 2/3 = (3*x1)/(4*x+2) cuzz 8/12 is 2/3 2=3*(3x1)/(4x+2) multiply both sides by 3 to have 2 by itself on the lhs(left hand side) with me stil :)
