Answer:
x ≤ 4
Step-by-step explanation:
1/2 x + 8 ≤ 10
1/2 x ≤ 10 - 8
1/2 x ≤ 2
x ≤ 4
The answer is the letter b cos u = 1 /sec u
When you use it in the left side of the identity that you want to verify, sec y cos y = 1 , you get this:
sec y cos y = 1
[sec y ] [ 1 / sec y ] = 1
[sec y] / [sec y] = 1
1 = 1 which proves the idenity.
