Answer:

<ABC = 80°

Step-by-step explanation:

find x first

<ABC = 1/2[(9x - 7) +(5x + 13)]

8x - 8 = 1/2(9x - 7 + 5x + 13)

16x - 16 = 14x + 6

2x = 22

x = 11

Plug in x = 11 into 8x - 8

<ABC = 8(11) - 8

<ABC = 88 - 8

<ABC = 80°

If QR= 3x-2, RS= 2x+1, QS=6x-3, and R is between Q and S, then RS=

rewona [7]

Answer:

RS = 5

Step-by-step explanation:

Since R is between Q and S , then

QS = QR + RS , that is

6x - 3 = 3x - 2 + 2x + 1

6x - 3 = 5x - 1 ( subtract 5x from both sides )

x - 3 = - 1 ( add 3 to both sides )

x = 2

Then

RS = 2x + 1 = 2(2) + 1 = 4 + 1 = 5
