we know that
The sum of the internal angles of a triangle must be equal to 
degrees
see the attached figure with letters to better understand the problem
m∠B+
°-----> by supplementary angles
m∠B=
m∠A=
m∠C=
m∠A+m∠B+m∠C=
Substitute
therefore
the answer is
the value of x is equal to 
You could subtract 5/4 from each side of the equation.
Then it would say
x = -2/4 .
That's a perfectly true solution, but not a very attractive one.
To pretty it up, you could simplify the fraction if you felt like it,
and you would have
x = -1/2 .

Answer:
x=4
Step-by-step explanation:
all you need to do is the 3rd root of 64
which is 4.
