Answer:

let's say x is equivalent to 3. now all x values are 3 so we can now we can solve the equation 3*3+2*3 squared -4*3+3*3 squared - 5*3, that equals 27.

Hello!

The sum of all angle measures in a heptagon in 900°. We will subtract all of these angles from 900 to find our answer.

900-146-122-142-140-110-142=98

x=98°

I hope this helps!

❥ $\Large\pmb{ \underline {\tt Answer}}$

So we can only find x if other two angles of triangle is given.

In angle B as u can see boxed shape angle is there then it probably means it's a 90° angle.

We know sum of angles of triangle = 180°

{Reson :-

There's a formula to fund sum of angles of figure

(n-2) × 180
(3 -2) × 180
1 × 180
180°

}

Now Let's proceed

$\boxed{ \rm Side_1+Side_2+Side_3 = 180\degree}$

Fill all the given values

$\dashrightarrow \tt 90 \degree + 55 \degree + c = 180 \degree$

$\\ \\$

$\dashrightarrow \tt 145\degree + c = 180 \degree$

$\\ \\$

$\dashrightarrow \tt c = 180 \degree - 145\degree$

$\\ \\$

$\dashrightarrow \tt c = 35\degree$

$\\ \\$

Value of x = 35°
