x = 4
-4x+21 => 5
Step-by-step explanation:
The given triangle in the picture is isosceles triangle which means that two sides of the triangle are equal.
So,

Now
Putting all the values in equation for perimeter

Putting x = 4 in side 1

Hence,
x = 4
-4x+21 => 5
Convert the fractions into decimals:
7/8 = 0.875
11/10 = 1.1
0.875 is 0.125 away from 1
and 1.1 is only 0.1 away from 1
So 11/10 is closer to whole number 1
