I'm going to assume that you are trying to find the two numbers. Based on the information in the problem, we can create the following equations (where
and
are the two numbers):


We have a systems of equations. In this case, it would be easier to use elimination by adding vertically. This produces the result:


To find
, substitute the value for
into one of the earlier equations:


The two numbers are 12 and 18.
It would be 8 to the 8th power
4m+9+5m-12=42
9m-3=42
Divide bothsides by 9.
9m/9 -3/9=-0.3=-4
m=-4
You need to know the properties of each function.
Tan is opposite (y) over adjacent (x). Sin>0 means that sin is positive, therefore, it is located on either quadrant 1 or 2. Tan=4/3 so it is located in quadrant 1.
The side of the triangle must be Adjacent=3 opposite=4 and hypotenuse=5
Now, you are asked to find the half angle of Cos which is

By following the formula, cos=3/5 then:

Multiply everything (inside the square

root) by 5


Then just simplify

The answer is Square root of 20 over 5
Answer:
y = 16/3
