Answer:
t = 9.57
Step-by-step explanation:
We can use trig functions to solve for the t
Recall the 3 main trig ratios 
Sin = opposite / hypotenuse
Cos = adjacent / hypotenuse 
Tan = opposite / adjacent. 
( note hypotenuse = longest side , opposite = side opposite of angle and adjacent = other side ) 
We are given an angle as well as its opposite side length ( which has a measure of 18 ) and we need to find its adjacent "t" 
When dealing with the opposite and adjacent we use trig ratio tan. 
Tan = opp / adj
angle measure = 62 , opposite side length = 18 and adjacent = t
Tan(62) = 18/t
we now solve for t 
Tan(62) = 18/t 
multiply both sides by t
Tan(62)t = 18
divide both sides by tan(62)
t = 18/tan(62) 
t = 9.57
And we are done!
 
        
                    
             
        
        
        
Since 52% is the same as 52/100, we can multiply 875 by 52/100 in order to find the green buttons. 
52/100(875) = 455

Answer: The correct answer is Choice C.
For this polynomial to be a perfect square, it would need to be:
(10x + 7)^2
This will ensure that the first terms and the last terms will be 100x^ and 49. However, if you use foil to multiply the factors, you will not get 150x for the center term. Choice C also states that 150x will not be the middle term.
        
             
        
        
        
A 40 degree angle: go from the right positive side of the x-axis and go left (left is positive degrees) forty degrees, which is a little less than halfway in quadrant 1.
