Answer: Choice A) Triangle ABC is similar to triangle ACD by AA
AA stands for Angle Angle. Specifically it means we need 2 pairs of congruent angles between the two triangles in order to prove the triangles similar. Your book might write "AA similarity" instead of simply "AA".
For triangles ABC and ACD, we have the first pair of angles being A = A (angle A shows up twice each in the first slot). The second pair of congruent angles would be the right angles for triangle ABC and ACD, which are angles C and D respectively.
We can't use AAS because we don't know any information about the sides of the triangle.
Answer:
6
Step-by-step explanation:
The absolute value of a non-negative number is the same number.
Example: The absolute value of 4 is 4.
If a number is negative, its absolute value is the same number, without the negative sign.
Example: The absolute value of -3 is 3.
Answer:
<h2><u>
15.12 is the discount</u></h2><h2><u>
68.88 is the sell price</u></h2>
Step-by-step explanation:
When you are taking off percentages from numbers, you first want to make the percent a number. This step is super simple. Just divide the 18 by 100
This gets you 0.18
Now multiply
84 * 0.18 = 15.12
So 15.12 is the discount
Then take 84 and subtract 15.12
84 - 15.12 = 68.88
So 68.88 is the sell price

2000+2000*0.005=2010
2010+2010*0.005=2020.05
2020.05+2020.05*0.005=2030.15025
Answer:
The solution is where the two lines intersept. Therefore, the answer is (4,2).
