Answer:
I don't know if this is correct but wouldn't it be 560?
Step-by-step explanation:
If you have 10 on one side, you divide 10 by 1/4 to get 40. So you need 40 blocks to fill one side, and 3 1/2 on the other only needs 14. 14*40=560.
C) $20
40 divided by 30 is 1.3
1.3 times 15 is 30
Add 65 and 85
65+85= 150
Next subtract 180-150
The answer is 30, so that is the missing angle is 30.
The side opposite to 30 is the shortest side
Here I added the picture!
Step 1: Flip the equation.
4.9p=44.1
Step 2: Divide both sides by 4.9.
4.9p= 44.1
4.9/4.9 = 44.1/4.9
p=9
