For this problem, you have to use sin, cos or tan. a way to remember which is which is this: soh cah toa. u also need to kmow the 3 sides of a triangle when looking at the angle. the 40 is on the hypotenuse side(the side across from the right angle, located by the square) it is represented by (H) the 25 is adjacent or(next to) the angle. therefore, you need to use cosine for this problem. so you would do cos(adjacent/hypotenuse) or (cah) so in the calculator put it in as cos(25/40)
Answer: $115 a month
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
Given
5x - 4 = - 3x + 12 ( add 3x to both sides )
8x - 4 = 12 ( add 4 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
The answer is: " 16 " .

Explanation:
____________________________
Method 1)
____________________________
(4/5) *(20/1) = ?
The "5" cancels to a "1" ; and the "20" cancels to a "4" ;
(since "20÷5=4" ; and "5÷5=1") ;
________________________________
Rewrite as: (4/1) * (4/1) = 4 * 4 = 16.
_________________________________
Method 2)
_______________________________
4/5 * 20/1 = (4*20)/(5*1) = (80/5) = 16 .
_________________________________
Method 3)
_________________________________
4/5 * 20 = ? ;
4/5 = 8/10 = 0.8 ;
0.8 * 20 = 16.0 = 16.
