Remember SOHCAHTOA
Sine- opposite/hypotenuse
Cosine- adjacent/hypotenuse
Tangent- opposite/adjacent
Look at the angle (x) you are trying to figure out and pick which one of these it is.
In your calculator, do the equation first to get a decimal
Then press whichever one you chose on the calculator, so if you got like 0.2 by doing opposite/adjacent for tangent, you would type in 0.2 and then the TAN button
hope this makes sense!!
Answer:
-31/9
Step-by-step explanation:
Bring -5/9 to other side
-4 is also written as -3 9/9
-3 9/9 + 5/9 = x
-3 4/9 = x
Answer:
Step-by-step explanation:
Before adding we require the fractions to have a common denominator
The lowest common denominator of 2, 5 and 3 is 30, thus
+ 
+ 
= 
+ 
+ 
Add the numerators leaving the denominator
= 
=
It totally depends on the value of 'a', and if 'a' changes, then (6a-2) immediately changes too. Whatever 'a' is at the moment, (6a-2) is 2 less than 6 times 'a'.
To solve this problem you must apply the proccedure shown below:
1. You have that 
varies jointly as 
and 
and inversely as the product of 
and 
. Therefore, you can write the following equation, where 
is the constant of proportionality:
2. Now, you must solve for the constant of proportionality, as following:
3. Susbtiute values:
4. Substitute the value of the constant of proportionality into the equation:
The answer is:
