Firstly, we will draw diagram of this problem
we are given
∠DAB=125º
∠ACB=30º
Since, ∠DAB is exterior angle
∠ACB and ∠ABC are interior angles
and we know that
exterior angle is sum of two interior angles
so, we get
∠DAB=∠ACB +∠ABC
now, we can plug values
125º=30º+∠ABC
∠ABC=95º.............Answer

Answer: Choice D) </h3>
y + 2 = -(x - 4)
============================================
Explanation:
The slope of this line is -1 because each time we move down 2 units, we move to the right 2 units. So slope = rise/run = -2/2 = -1
The slope formula says the same thing more or less. Let's pick the two points (0,2) and (2,0) to find the slope through them
m = (y2-y1)/(x2 - x1)
m = (0-2)/(2-0)
m = -2/2
m = -1
-------------
Using that slope and a point on the line, we can form the equation. We can pick any point really as long as it's on the line. However, to have it match with the answer choices, we'll have to pick the point (4,-2)
Turn to point slope form
y - y1 = m(x - x1)
y - y1 = -1(x - x1) ... plug in the slope
y - (-2) = -(x - 4) ... plug in the point (x1,y1) = (4, -2)
y + 2 = -(x - 4)

Step-by-step explanation:
Answer:
x = -9
Step-by-step explanation:
6x-22+2x=8x-4
so first you want to add 4 to both sides so it becomes 6x-18=8x now substract 6x from both sides to get -18=2x now divide that by 2 and you get x= -9
Y = sin x
y' = cos x
y'' = -sin x
y''' = -cos x
y'''' = sin x
Therefore, nth derivative of sin x = sin(nπ/2 + x)
