Answer:

The value of x is $x = 274 \ unites$

Step-by-step explanation:

From the question we are told that

The length of the vertical length is $x$

The length of the base leg is L = 330 + d units

The length of the bisecting line segment is h

The base angle is $\theta = 28^o$

The angle between d and line segment is $\theta_1 = 56^o$

For the first angle

$Tan \theta_1 = \frac{x}{d}$

=> $d = \frac{x}{Tan \theta _1}$

For the whole big triangle

$Tan \theta = \frac{x}{330 + d}$

=> $d = \frac{x}{Tan \theta } -330$

So equating the both d

$\frac{x}{Tan \theta _1} = \frac{x}{Tan \theta } -330$

Substitute values

$\frac{x}{Tan (56)} = \frac{x}{Tan (28) } -330$

$0.6745 x = 1.880x -330$

$1.20549 x = 330$

$x = 274 \ unites$

1.

$g+h=-7+3=\boxed{-4}$

2.

$g-h=-7-3=\boxed{-10}$

3.

$h-g=3-(-7)=3+7=\boxed{10}$

4.

$gh=-7\cdot3=\boxed{-21}$

5.

$g+h^2=-7+3^2=-7+9=\boxed{2}$

6.

$g^2-h=(-7)^2-3=49-3=\boxed{46}$
