The ratio of coins to notes in a bag is 3 to 8. If there are a total of 24 coins then how many notes are there? 
BaLLatris [955]
Set up a proportion 
3 coins:8 notes and then the other one 24 coins : x (unknown notes)
they have a relationship so we can set them equal to each other.
3/8=24/x cross multiply: 8 * 24 = 192
Now divide that by 3: 192/3 = 64 
So there are 64 notes in the bag

Answer:

<h2>∠HFG = 115°</h2>

Step-by-step explanation:

∠JFG + ∠HJF = 180° <em>[Adjacent angles of parallelogram are supplementary] </em>

<em>∠</em>JFG = 65°

=> 65° + ∠HJF = 180°

=> ∠HFG = 180° - 65°

=> ∠HFG = 115°
