Answer:

Sum of interior angles of 12 sided object = 1800°

Step-by-step explanation:

Formula to calculate the sum of interior angles of a polygon is,

Sum of the interior angles of a polygon = (n - 2) × 180°

Where n = number of sides of the polygon.

If number of sides of a polygon are 12,

For n = 12,

Sum of interior angles = (12 - 2) × 180°

                                     = 10 × 180°

                                     = 1800°

Therefore, sum of interior angles of a 12 sided polygon will be 1800°.

In parallelogram the opposite sides are equal. Therefore we have the equation:

8a-4=6a+10\ \ \ |+4\\\\8a=6a+14\ \ \ |-6a\\\\2a=14\ \ \ |:2\\\\\boxed{a=7}

In the parallelogram, the sum of measures of the angles at one side is 180°. Therefore we have the equation:

(18b-11)+(9b+2)=180\\\\(18b+9b)+(-11+2)=180\\\\27b-9=180\ \ \ |+9\\\\27b=189\ \ \ \ |:27\\\\\boxed{b=7}

Answer:

c = a + b → c = 7 + 7 = 14

A. 14

Therefore,
186/6=31 pounds
Its difference is 186-31=155

Which equation below would match this graph?
ch4aika [34]
A

The y-intercept is y=3

Any number to the ^0 = 1. Because the y-intercept is 3, that means it was multiplied by 3 to get that y value, which is why a is correct.

Finger [1]

Answer:

  • x = -8.5
<h3><u>Step-by-step explanation:</u></h3>
  • 2(x + 3.5) = -10
  • => 2x + 7 = -10
  • => 2x = -10 - 7
  • => 2x = -17
  • => x = -8.5
<h3><u>Conclusion:</u></h3>

Therefore, the answer is x = -8.5.

Hoped this helped.
