Need help with this asap!
My name is Ann [436]

Answer:

Step-by-step explanation:

1 )  2 + 7t                        [ there are no like terms , so no further simplifying ]

2) 6r + ( - 16 r )

   =  6 r - 16 r                 [ both are like terms ]

   = - 10 r

3) (3x + 2 ) + ( 2x - 4 )

   = 3x + 2 + 2x - 4

   = 3x + 2x - 4 + 2               [ arranging like terms together ]

   = 5x - 2

4) (8 n² - 3 n + 6 ) + ( n - 2 )

   = 8n² - 3n  + 6 + n - 2

   = 8n² - 3n + n + 6 - 2             [ bringing like terms together ]

   = 8n² - 2n + 4

Please please please help me i really need help<br><br> angle c = ___ degrees
OlgaM077 [116]

Answer:

angle c = <u>83</u> degrees

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral add up to 180 degrees.

According to the rule, <D and <B add up to 180° and same for <A and C.

This means that the sum of (x + 100) and (3x) equal 180.

Therefore (x + 100) + (3x) = 180 →

4x + 100 = 180

–100 –100

4x = 80

÷4 ÷4

x = 20.

Since x = 20, <A = 5x – 3 = 5(20) – 3 = 97.

Since <A + <C = 180.

97 + <C = 180 → 97 + <C = 180

–97 –97

<C = 180 – 97 = 83°
