Step-by-step explanation:
<u>WE HAVE TO USE PYTHAGORAS!</u> ⇒ a²+b²=c² THEN √c = (unknown side)
Here: 12² + 8²= 208
Now SQUARE-ROOT 208! ⇒ √208
ANSWER: 14.42220510185596
The answers there are rounded up so we round this number to get 14m!

1st answer
Step-by-step explanation:
First you subrtract 3 from 0 then add 4 to -3
Your answer would be 135.
This is because angles on a straight line add up to 180°, and so we need to subtract 45 from 180, which gives us 135.
I hope this helps!
Answer:
carbon footprint
7.7 tons
Step-by-step explanation:
Given that,
carbon dioxide produced by a car over 7 year period = 53.5 tons
To find,
carbon footprint <em>(tons of carbon dioxide per year)</em>
7 years ------> 53.5 tons
1 year -------> 53.9/7 tons
= 7.7 tons
tons of carbon dioxide produced per year = 7.7
