HCl and NH3 is a covalent compound but their aqueous solutions conduct electricity give reason​

Answer:

x=87° will be the answer of this question as the two horizontal lines are parallel because 57°and 57° are equal so the line sare parallel and angle W=87° will be equal to angle V=87° so angle TVY will be also 87° because they arevertically opposite angles.

Answer:

X = 87°

Step-by-step explanation:

• When two lines intersect, the vertically opposite angles so formed are equal.
• If two parallel lines are intersected by a transversal,

1. Each pair of corresponding angles is equal.
2. Each pair of alternate interior angles is equal.
3. Each pair of interior angles on the same side of the transversal is supplementary.

The angle 87° given in the figure and ∠UWV form vertically opposite angles.

We know that vertically opposite angles are equal,

∴ ∠UWV = 87°

∠UWV and x form a pair of corresponding angles, when transversal Y intersects the two parallel lines.

Since corresponding angles are equal,

x = ∠UWV

∴ x = 87°
