Answer:

\Huge \boxed{x=-2.5}

Step-by-step explanation:

<em>Add by 5.1 from both sides of equation.</em>

<em>\displaystyle x-5.1+5.1=-7.6+5.1</em>

<em>Simplify, to find the answer.</em>

<em>\displaystyle -7.6+5.1=-2.5</em>

<em>\boxed{x=-2.5}, which is our answer.</em>

Answer:

The value of x is 105°

Step-by-step explanation:

Firstly, you have to find the total angles in regular hexagon and octagon using the θ = (n-2)×180° where "n" determine numbers of edges :

hexagon,

θ = (6-2)×180°

= 4 × 180°

= 720° (total angles)

octagon,

θ = (8-2)×180°

= 6 × 180°

= 1080° (total angles)

Then, calcular the angle for each edge :

hexagon,

θ = 720° ÷ 6

= 120°

octagon,

θ = 1080 ÷ 8

= 135°

Lastly, to find the value of angle x. As the angle in a circle is 360° so you have to substract :

x = 360° - 135° - 120°

= 105°

The angle measurements in the diagram are represented by the following expressions
krok68 [10]

Answer:

/A = 30°

/B = 150°

Step-by-step explanation:

Given that the lines are parellel.

Then /A+/B = 180° ( Consecutive interior angles)

Putting given values of angles

6x-18+ 14x+38 = 180

20x + 20 =180

20x = 160

x = 8

/A = 6x-18 = 6×8-18 = 30°

/B = 14x+38 = 14 × 8 +38 = 150°
