There are 7 humans and 15 dogs
7+15= 22 heads
7×2=14 legs for humans
15×4=60 legs for dogs
14+60=74 legs
The sum of all the angles of any triangle is 180 degrees
--> Therefore the missing angle is:
<u>x = 180 - 60 - 75 = 45</u>
Hope that helps!
The length of the parallelogram is 18 meters.
The width of the parallelogram is 16 meters.
The problem should be 7.5=3k. So that means that you have to divide both sides by 3. Once you do that you should get 2.5 as your answer.
