Answer:
Step-by-step explanation:
In each case, draw the right triangle which produces the inverse trig value. That is, label the two sides as needed, and calculate the third side.
It should be clear that
sin(2α) = 2 sinα cosα
So,
See what you can do with the others.
<u>Answer:</u>
1/9 > -4
because -4 is a negative no less than 0. whereas 1/9 is a positive no greater than 0.
So negative no can't be greater than positive no.
2(4z - 6 - 6) = 170 - 46
2(4z - 12) = 124 |use distributive property: a(b - c) = ab - ac
8z - 24 = 124 |add 24 to both sides
8z = 148 |divide both sides by 8
z = 18.5
Here u go. It says my answer has to be at least 20 words long so I'm just typing for no reason. Lol.
