Answer:
XZ ≈ 14.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos29° = 
= 
= 
Multiply both sides by XZ
XZ × cos29° = 12.6 ( divide both sides by cos29° )
XZ = 
≈ 14. 4 ( to 3 sig. figs )
Answer:
2 feets
Step-by-step explanation:
Given that :
Alli's Initial depth = 6 feets
Number of feets in which Alli rose = 4 feets
Alli's new position relative to the surface of the pool:
Difference of Alli's initial depth and feets risen :
6 feets - 4 feets = 2 feets
Hence, Alli is now 2 feets below the surface of the pool.
