Answer: 
Step-by-step explanation:
As X is an acute angle, all 6 trigonometric functions with an argument of X are positive.
Using the identity
,

Answer:
16
Step-by-step explanation:
The differnce of 28 and 12 is 16 because, 28-12=16 and 16+12=28
Answer:
○ C. The lines are perpendicular.
Step-by-step explanation:
In order for equations to be perpendicular, their <em>rate of changes</em> [<em>slopes</em>] must be OPPOSITE <em>MULTIPLICATIVE</em><em> </em><em>INVERSES</em>, which in this case is so:
− to +}
> OPPOSITE
+ to −}
MULTIPLICATIVE INVERSE [RECIPROCAL]

Hi rainy here !!! so lets see lets set up your problem like this
X/1280 = 60%/100 so lets cross multiply
100 times X =100X
60 times 1280 = 76800
100X=76800 now lets divide each side by 100
100 divided by 100 = 0
76800 divided by 100 = 768
X=768
So now we have to subtract to get the total amount so 1280 minus 768 = 512
512 is your answer :)
Hope I helped if u have any questions on how I did your problem feel free to message me or comment on my page bye !!!

Answer:
y - 3 = -1/2(x-1)
Step-by-step explanation:
Given the coordinates (1, 3) and (5,1). The point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the required point
Get the slope
m = 1-3/5-1
m = -2/4
m = -1/2
Using the point (1,3), substitute
y - 3 = -1/2(x-1)
2(y-3) = -(x-1)
Hence the required equation is y - 3 = -1/2(x-1)
