Cole is an urban planner. He wants to create a small scale drawing of a city block. The block is a square with side length 90 m
Draw the city block such that 1 unit on the grid below represents 30 m.

i think the correct option is the second option.

1. supplementary angles

2. acd and bcd

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
