Answer:

B. all of these are true

Step-by-step explanation:

natali 33 [55]

Answer:

36 minutes

Step-by-step explanation:

Depth of the fjord = 1308 m

Rate at which the submersible dives = 35 meters/minute

Distance to the bottom of the fjord should be 48 m

Distance the submersible has to go underwater is $1308-48=1260\ \text{m}$

Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

$\dfrac{1263}{35}=36\ \text{minutes}$

The time taken by the submersible to dive the required distance is 36 minutes.

Hi, can you help me to find (if passible) the complement andsupplement of the angle 3pi/ 4.

nika2105 [10]

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.

In radians this are

$\begin{gathered} \frac{\pi}{2}\text{ for }90\degree \\ \pi\text{ for }180\degree \end{gathered}$

To find the complement of 3π/4, subtract it by π/2

$\frac{\pi}{2}-\frac{3\pi}{4}=-\frac{\pi}{4}$

To find the supplement of 3π/4, subtract it by π.
