Question

The value of x is

  1. 5
  2. 4
  3. 3
  4. 2

hintHint:

Compare the congruent sides of the triangles to find x.

The correct answer is: 5


    I n space t h e space g i v e n space f i g u r e s comma
T h e space s i d e space open parentheses 7 x space minus space 4 close parentheses space o f space o n e space t r i a n g l e space i s space c o n g r u e n t space t o space t h e space s i d e space 31 space o f space t h e space o t h e r space t r i a n g l e.

H e n c e comma
7 x space minus space 4 space equals space 31
7 x space equals space 31 space plus space 4
7 x space equals space 35
x space equals open parentheses 35 over 7 close parentheses
x space equals space 5

T h e r e f o r e comma space x space equals space 5

    You can also find the value of y by this method.
