Answer:
x=21
Step-by-step explanation:
We know that C is a right angle, which means that x + 3x+6 = 90
Have a nice day. hope I helped please rate brainliest!
Answer:
sin(T)
cos(C)
Step-by-step explanation:
sine goes up or down for angles in the circle.
cosine goes left or right for angles in the circle.
consider a circle with is center at T, and it goes through C (so, the radius is 25 = TC).
then 7 = sin(T)×25
24 = cos(T)×25
so, sin(T) = 7/25
then, sin(T) = cos(90-T)
and the angle at C = 90-T.
therefore, cos(C)=sin(T)=7/25
tan(x) = sin(x)/cos(x)
and that would lead here always to a 7/24 or 24/7 ratio.
so, no tan function is right.
Answer:
>
Step-by-step explanation:
Divide them, Do 2 divided by 5 and you'll get 0.4 and then do 35 divided by 100 and you'll get 0.35. 0.4 is bigger then 0.35 so the answer will be >.
We have been given the expression to be 
Since we need to find the tangent at a point, we will have to find the derivative of 
as the slope of the tangent at a given point on the curve is always equal to value of the derivative at that point.
Thus, we have to find 
We will use the product rule of derivatives to find 
Thus, 
(using the product rule which states that 
)
Taking the common factors out we get:
Thus, 
at 
is given by:
=Slope of the tangent of y at x=4=
Thus, 
Now, the equation of the tangent line which passes through 
and has slope m is given by:
Thus, the equation of the tangent line which passes through 
and has the slope 185 is
Which can be simplified to 
Thus, 
This is the required equation of the tangent.
Answer:
Step-by-step explanation:
Y=3x-4
Slope of this line = 3
Slope of the line parallel to this line = 3 {slope of parallel lines are equal}
Slope of the line perpendicular to this line = -1/3 {product of the slope of perpendicular lines= -1}
