The value of x is 155.

Step-by-step explanation:

We know that:

35 + 90 + a = 18090 + (180 - x) + (180 - a - 60) = 180

Let's first simplify the first equation.

=> 35 + 90 + a = 180=> 125 + a = 180=> a = 180 - 125=> a = 55

With the help of the 'a' value, let's find the value of x using the second equation.

=> 90 + (180 - x) + (180 - a - 60) = 180=> 90 + (180 - x) + (180 - 55 - 60) = 180=> 90 + (180 - x) + (125 - 60) = 180=> 90 + (180 - x) + 65 = 180=> 155 + 180 - x = 180=> 335 - x = 180=> 335 - 180 = x=>

Hence, the value of x is 155.
