Ab= 6cm Ac=12cm <br> Calculate the length of Ad <br> Give your answer to 3 significant figures

Allisa [31]

Answer:

12.686cm

Step-by-step explanation:

By using pythagoras, we can find CB.

We know that $a^2+b^2=c^2$

Therefore, $12^2-6^2=CB^2$

$CB=\sqrt{108}$ (it has to be positive since it is distance)

now we look at triangle BCD and use SOH CAH TOA.

$Sin55=CB/CD\\Therefore, CD= 12.686$

At midnight, the temperature was -8oF. At noon, the temperature was 23oF. Which expression represents the increase in temperatur

irinina [24]

Answer:

$23^oF-(-8^oF)$

Step-by-step explanation:

We have been given that at midnight, the temperature was $-8^oF$ . At noon, the temperature was $23^oF$ .

Since our temperature has increased to 23 degree Fahrenheit from -8 degree Fahrenheit, we can represent this increase in temperature as:

$\text{The increase in temperature}=23^oF-(-8^oF)$

Therefore, the expression $23^oF-(-8^oF)$ represents the increase in temperature.
