Given:
The figure of a right triangle ABC.
To find:
The trigonometric ratios 
.
Solution:
Using Pythagoras theorem,
Taking square root on both sides.
So, measure of BC is 8 units.
Now,
Similarly,
And,
Therefore, the required trigonometric ration are 
.
The answer to that would just be 18 if you want the word in number form, I'm actually kinda confused on what your question means
Answer:
1386 in³
Step-by-step explanation:
Volume of the composite cone = volume of a hemisphere + volume of a cone
=>Find the volume of cone
Volume of cone = ⅓πr²h
π = 3.142
r = 7 in
h = =√(15² - 7²) [using Pythagorean theorem to solve for height given the slant height and radius]
h = √(225 - 49)
h = √176 ≈ 13 in
Volume of cone = ⅓*3.142*7²*13
= ⅓*2001.454 ≈ 667 in³
=>Find volume of hemisphere.
Volume of hemisphere = ½*volume of sphere = ½*4/3πr³ = ⅔πr³
π = 3.142
r = 7 in
Volume = ⅔*3.142*7³ ≈ 719 in³
<em>Volume of composite figure = 667+719 = 1386 in³</em>
3/8
Just divide to find the equal decimal.
3/8 = 0.375
