Answer:
Cos θ = 13/15
Tan θ= 12/13
Step-by-step explanation:
We are given;
Sin θ = 12/15
From trigonometric ratios, we know that;
Sin θ = opp/hyp
Cos θ = adj/hyp
Tan θ = opp/adj
Thus, since Sin θ = 12/15, then;
Adjacent side = √(15²- 12²)
Adhacent side = √169
Afjacent side =13
Thus;
Cos θ = 13/15
Tan θ= 12/13
It will take them about 26 days to complete the expedition
<h2>Proportion and distance</h2>
According to the information, the team of explorers is to travel 19.12km in 12 hours
If they are expected to travel 1014.15km in total, the total time taken is given as:
1014.15km = x
Take their proportions:

Convert the time taken to days;

This shows that it will take them about 26 days to complete the expidition.

Answer:
12,167 ft^3
Step-by-step explanation:
To find the volume of something, you simply multiply the length times width times height. The equation looks like this; 
A cube has equal measures of all sides-
23*23*23=12167
