Given an angle and a side of a right angle triangle, you can use the appropriate ratio to find the missing side.
For instance, find x in the diagram in the attachment.
In this case the best ratio to use is TOA.
All the other ratio also follow the same pattern

1
Step-by-step explanation:
3/11 *3/11
2nd 3/11 flips over. Then multiply. Then u get 33/33 which equals 1
Answer:
2 sqrt(2x-1)
Step-by-step explanation:
f(x) = sqrt( x+9)
g(x) = 8x-13
f(g(x))
place the function g(x) in for x in f(x)
f(g(x)) = sqrt(8x-13+9)
Combine like terms
f(g(x)) = sqrt(8x-4)
Factor out 4
f(g(x)) = sqrt(4*(2x-1)
2 sqrt(2x-1)
