This is what I got hope it’s right
Given:
In a right angle triangle ABC, altitude BD drawn to hypotenuse AC.
AD=3 and, AC=27.
To find:
The length of AB.
Solution:
Draw a figure by using the given information as shown below.
In triangle ABC and ADB,
(Right angles)
(Common angle)
(AA similarity postulate)
We know that the corresponding parts of congruent triangles are proportional. So,
![\dfrac{AC}{AB}=\dfrac{AB}{AD}](https://tex.z-dn.net/?f=%5Cdfrac%7BAC%7D%7BAB%7D%3D%5Cdfrac%7BAB%7D%7BAD%7D)
After substituting the given values, we get
![\dfrac{27}{AB}=\dfrac{AB}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B27%7D%7BAB%7D%3D%5Cdfrac%7BAB%7D%7B3%7D)
![27\times 3=AB\times AB](https://tex.z-dn.net/?f=27%5Ctimes%203%3DAB%5Ctimes%20AB)
![81=AB^2](https://tex.z-dn.net/?f=81%3DAB%5E2)
Taking square root on both sides, we get
![\sqrt{81}=AB](https://tex.z-dn.net/?f=%5Csqrt%7B81%7D%3DAB)
![9=AB](https://tex.z-dn.net/?f=9%3DAB)
Therefore, the length of AB is 9 units.
0.000005,first combine them together. equal to 10^-5/2. then you solve 10^-5 equal 0.00001,so it like this : 0.00001/2 equals 0.000005. if there's still problem just ask me
Answer:
The answer would be that she has an weekly allowance of 16$
Step-by-step explanation:
First you found out that she had 12$ at the end of the week so it said she washed her parents car for 4$ but that isnt part of her weekly allowance so you would subtract by 4 and get 8. Then it says she spent half of it on mini golf so you times it by two and get an allowance of 16$ :)
