HOW TO FIND THE MISSING SIDE OF A TRIANGLE USING SIMILAR TRIANGLES

 

steps:

x over the equivalent known side

=

the known value from “x”‘s triangle over the equivalent value from the other triangle

then, multiply x by the denominator in its fraction. cross out the denominator and the notation of the multiplication.

next, multiply the numerator of the second fraction by the denominator of the first. take that product and divide it by the second fraction’s denominator.

that quotient is your answer!
