Use the formula   i = p*r*t:
                                                               $456
$456 = $1600*r*6.  Solving for r, r = ----------------- = 0.0475, or 4 3/4%
                                                           ($1600)(6)
        
             
        
        
        
Hello.
To find the answer of this question, you need to find 6% of 598. 
6 / 100 = 0.06. 0.06 x 598 = 35.88. So now all you have to do is subtract 35.88 from 598. 598 - 35.88 = 562.12.
So the new price of the television is 562.12.
Have a great day! :)
        
             
        
        
        
The cosine is the ratio of hypotenuse and base. Then the measure of the angle ∠L will be 60°.
<h3>What is trigonometry?</h3>
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The right-angle triangle is given below.
The length of the hypotenuse is 16 and the base length is 5. 
Then the measure of the angle ∠L will be 
cos L = 5 / 10
cos L = 1 / 2
       L = cos⁻¹ (1 / 2)
       L = 60°

X = 4(180 - x)
x = 720 - 4x
4x + x = 720
5x = 720
x = 720/5
x = 144
180 - x =
180 - 144 =
36
the measure of the angle is 144...the measure of its supplement is 36
