45 degrees for x.
Do 180-160 = 20 (Since 180 is a straight line)
The 115, x, and 20 form another straight line, so take 180-20-115. You get 45.

David is shoveling driveways to raise money for his Spring
Anna007 [38]

Answer:

Total savings  = $63  +  12 ( m)  

: m  = number of driveways shoveled

Step-by-step explanation:

Here, the money earned for each road David shovels = $15

The number of driveway shoveled by David = 12

The total money saved  David has after he is done with his work = $243

Now, The number of money saved by shoving 12 driveways  

= 12 x ( Money earned by shoveling 1 driveway)

= 12 x ( $15) = $ 180

Total savings  = His previous savings  + Money earned from Shovel work

⇒  $243  =   His previous savings + $ 180

⇒ His previous savings = $243  - $180 = $63

Now, we can write his total savings as:

Total savings  = $63  + 12 ( m)  

: m  = number of driveways shoveled
