Find the value of x!?!??!!

Step-by-step explanation:

70+85+150+x=360 degree(sum of 4 angles is always 360 degree)

305+x=360

x=360-305

x=55 degree

85+1 50+70+x=360{ sum of interior angels of of quadrilateral}

305+x=360

x=360-305

x=55degree

answer: idk

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
