I need a answer to m
Thanks

The answer to your question is ∠Z = 119°

Step-by-step explanation:

Data

∠W = 41°

∠Y = 81°

∠Z = ∠X = ?

Process

To solve this problem use the law that states that the sum of the internal angles in a quadrangle equals 360°.

1)

         ∠W + ∠Y∠ + ∠X + ∠Z = 360°

2.- Simplify

         ∠W + ∠Y + 2∠Z = 360

3.- Substitution

         41° + 81° + 2∠Z = 360

4.- Solve for Z

                           2∠Z = 360 - 41 - 81

                           2∠Z = 238

                              ∠Z = 238/2

                             ∠Z = 119°

range is infinite on both x and y axis positive and negative

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
