3 0

Answer:

(-3,-1.5)

Step-by-step explanation:

The two points are: (-2,1) & (-4,-4)

x =  \frac{ - 2 - 4}{2}  =  - 3 \\  \\ y =  \frac{1 - 4}{2 }  =  -  \frac{3}{2}  =  - 1.5

Explain how you determined each of the numbered angle measures.
nalin [4]

The numbered angle measured is ∠1 = 61°, ∠2= 119, ∠3 = 61, ∠4 = 119, ∠5 = 119, ∠6 = 61 , ∠7 = 119

In this figure, we have

∠8 = 61°

Now, To find the

∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7

Now, Let's take the ∠7 and ∠8

and, firstly find the ∠7

We know that the sum of two angles is 180°

and, Given the  ∠8 = 61°

∠7 + ∠8 = 180° (Linear Pair of Angles)

∠7 + 61° = 180°

∠7  = 180° - 61°

∠7 = 119°

and, ∠5 = ∠7 = 119° (Vertically opposite angle)

and, ∠1 = ∠8 = 61° (Corresponding Angles)

∠1 = 61° and ∠2 is the supplementary angle to given angle

So, ∠1 + ∠2 = 180°

where, supplementary angles are two angles whose measured add up to 180°

61° + ∠2 = 180°

∠2 = 119°

and ∠5 + ∠6 = 180°(Corresponding angle with ∠5)

119°+∠6 = 180°

∠6 = 180 = 119

∠6 = 61°

and, ∠3 = ∠6 = 61° (Corresponding Angle)

∠4 = ∠7 = 119° (Corresponding angle)

Hence, The numbered angle measured is ∠1 = 61°, ∠2= 119, ∠3 = 61, ∠4 = 119, ∠5 = 119, ∠6 = 61 , ∠7 = 119
