If EF - 3x - 11, FG = 4x-10, and EG - 28, find the values of x, EF, and FG. The drawing is not to scale.
Gnom [1K]

Answer:

Part 1) x=7

Part 2) EF=10\ units

Part 3) FG=18\ units

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

EG=EF+FG ---> by addition segment postulate

we have

EG=28\ units\\EF=3x-11\\FG=4x-10

substitute

28=(3x-11)+(4x-10)

solve for x

28=7x-21

7x=28+21

7x=491

x=7

step 2

Find the value of EF

EF=(3x-11)

substitute the value of x

EF=3(7)-11=10\ units

step 3

Find the value of FG

FG=(4x-10)

substitute the value of x

FG=4(7)-10=18\ units
