Step-by-step explanation:

Sum of interior angles of a polygon is given by (n-2)180°

where,n is the number of sides.

Since this polygon has 4 sides,

sum of the interior angles = (4-2)180°=360°

x+115°+95°+70°=360°

x°=360°-280°

= 80°

Answer:

x = 80

Step-by-step explanation:

In a quadrilatoral the interior angle sum always adds up to 360 degrees so to find x you would add all of the interior angle sums and subtract that from 360

115 + 95 + 70 + x = 360     just add the like terms

280 + x = 360                 now subtract 280 from both sides so x is alone and you can figure out its value

x= 80

 y = - 4x + - 8 is equation of slope-intercept form.

What is in slope-intercept form?

  • Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
  • Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.

the equation of slope - intercept form

                               y = mx + c

( -1 , -4 ) is point shown in graph

            slope = -y/x

                     = - ( -4)/-1  = 4/-1 = -4

             - 4 = -4 * - 1 + c

            - 4 = 4 + c

            c = - 4 - 4 = - 8

put value of c in the equation of slope - intercept form

             y = - 4x + - 8

Please Help!! What is the next step in the proof? Choose the most logical approach.
marta [7]

Answer:

statement D is correct.

<em>Statement: ∠7 ≅ ∠6 and ∠8 ≅ ∠5</em>

<em>Reason: Vertical Angles Theorem</em>

Step-by-step explanation:

Given that

3 ≅ ∠7 and ∠4 ≅ ∠8

from statement 2 because they are corresponding angles.

∠8 ≅ ∠5

because its vertical angles

The vertical angles theorem is about angles that are opposite each other.

So,

∠4 ≅ ∠8 and ∠8 ≅ ∠5

which means

<h3> ∠4 ≅ ∠5 </h3>

Hence,

∠3 = ∠7

∠4 = ∠5

they are known as interior alternative angles.

In a shipment of 600 parts, 30 are found to be defective. How many defective parts should be expected in a shipment of 1000?
kobusy [5.1K]
We can except 30/600 = 0.05>> 5%percent,
so 1000 * 0.05 = 50 parts defective
