Given:
• AD = 3
,
• DC = 27
,
• BD = x + 3
Let's solve for x.
To solve for x, apply the altitude formula:
![\frac{AD}{BD}=\frac{BD}{DC}](https://tex.z-dn.net/?f=%5Cfrac%7BAD%7D%7BBD%7D%3D%5Cfrac%7BBD%7D%7BDC%7D)
Where BD is the altitude.
Cross multiply:
![BD^2=AD*DC](https://tex.z-dn.net/?f=BD%5E2%3DAD%2ADC)
Plug in the values and solve for x:
![\begin{gathered} (x+3)^2=3*27 \\ \\ (x+3)^2=81 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%28x%2B3%29%5E2%3D3%2A27%20%5C%5C%20%20%5C%5C%20%28x%2B3%29%5E2%3D81%20%5Cend%7Bgathered%7D)
Take the square root of both sides:
![\begin{gathered} \sqrt{(x+3)^2}=\sqrt{81} \\ \\ x+3=9 \\ \\ \text{ Subtract 3 from both sides:} \\ x+3-3=9-3 \\ \\ x=6 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csqrt%7B%28x%2B3%29%5E2%7D%3D%5Csqrt%7B81%7D%20%5C%5C%20%20%5C%5C%20x%2B3%3D9%20%5C%5C%20%20%5C%5C%20%5Ctext%7B%20Subtract%203%20from%20both%20sides%3A%7D%20%5C%5C%20x%2B3-3%3D9-3%20%5C%5C%20%20%5C%5C%20x%3D6%20%5Cend%7Bgathered%7D)
Therefore, the value of x is 6 .
ANSWER:
d. 6
Answer:
5,280
Step-by-step explanation:
6600 x 20 = 132,000
132,000 / 100 = 1320
6600 - 1320 = 5280

Put 5 in place of n in the equation.
6.5(5)+4.5
5^2+5
Then you should find your answer.
If it helps, think of f(n) as y.
Answer:
286.5 degrees
Step-by-step explanation:
We want to change radians to degrees
2 pi radians = 360 degrees
5 radians * 360/ 2 pi
900/pi degrees
286.4788976 degrees
286.5 degrees
410 × 0.393 =161.13
