lubasha [3.4K]

Here,

m II n

5x + 13 and 143 are corresponding angles.

So,

5x + 13 = 143

Substract 13 on both sides,

5x = 143 - 13

5x = 130

Divide 5 on both sides,

x = 130 / 5

x = 26

LiRa [457]

Answer: 3000 stamps

Step-by-step explanation:

Given

Chris and Josh have 1800 stamps

Josh and Jessica have 2200 stamps

Jessica and Chris have 2000 stamps

Suppose Chris, Josh, and Jessica have $x,y, \text{and}\ z$ stamps

$\therefore x+y=1800\quad \ldots(i)\\\Rightarrow y+z=2200\quad \ldots(ii)\\\Rightarrow z+x=2000\quad \ldots(iii)\\\text{Add (i), (ii), and (iii)}\\\Rightarrow 2(x+y+z)=1800+2200+2000\\\Rightarrow x+y+z=3000$

Thus, all three have 3000 stamps
