Answer:
A is the correct answer
Step-by-step explanation:
As the question is asking what simple is the correct one and the lines sorry I forgot what the name of them is. Then lines make negatives positive it does not effect a positive number as the number is positive.
Answer:1
1. 
2. ∠ABC = 120°, ∠BCD = 90°, ∠CDA = 60°, ∠DAB = 90°
Step-by-step explanation:
It's important to note here that the measure of all interior angles in a quadrilateral will add up to 360°
We know this using the formula
, a 4 sided figures angles will add up to
This means that all of the angles (4x, 3x, 2x, 3x) will add up to 360.
Combine like terms:
Divide both sides by 12:
We know now substitute x for 30 in for all of the side lengths.
∠ABC = 4x = 
°
∠BCD = 3x = 
°
∠CDA = 2x = 
°
∠DAB = 3x = °
Hope this helped!
Answer:
(cos^2 y) /(1-sin y) = (1 - sin^2 y) / (1-sin y) = ((1-sin y)(1+sin y)) / (1-sin y) = 1+sin y
50% were invested in land, 10% were invested in stocks and 20% were invested in bonds.
Based on this, the total percentage of investments can be calculated as follows:
percentage of investments = 50% + 10% + 20% = 80%
The remaining percentage that was put into a saving account can be calculated as follows:
percentage of money in saving account = 100% - 80% = 20%
Now we know that the remaining is $35,000 represent the 20% of his money.
Assume his total amount of money is m, therefore:
20% x m = 35000
0.2m = 35,000
m = (35,000) / 0.2 = 175,000
Based on this, <span>the total amount of money that Mr. Rodriguez saves and invests is $175,000</span>
