Answer:
-3/5
Step-by-step explanation:
10-8/4-12=-0.6=-3/5
Scientific notation = 4.1 x 10^9
Decimal notation = 4,100,000,000
Answer:
x = 55.6
Step-by-step explanation:
Recall the 3 main trig functions
Sin = opposite / hypotenuse
Cos = adjacent / hypotenuse
Tan = opposite / adjacent
Note that hypotenuse = longest side length
We want to find angle "x".
We are given its opposite side length ( 19 ) as well as the adjacent side length
When dealing with the opposite and adjacent we use tan
Tan = Opp / Adj
Opp = 19 and Adj = 13
Tan(x) = 19/13
* take the inverse tan of both sides *
x = 55.6
The answer is x is less than or equal to 3. the first answer choice
