Answer:
x = 4
8(4) - 2 = 30
15(4) = 60
All triangles equal 180 degrees and there is already a right angle. 60 plus 0 is 90, and 90 plus 90 (or 90 times 2) is 180
60 + 30 = 90
90 + 90 = 180
Step-by-step explanation:
Answer:
The
,
and
.
Step-by-step explanation:
The given function is
.... (1)
The general form of sine function is
....(2)
where, |A| is the amplitude, B is period, D is the vertical shift (up or down), and C/B is used to find the phase shift.
On comparing (1) and (2), we get




So,



Therefore
,
and
.
Answer: y + 2 =
( x - 4 )
Step-by-step explanation:
The equation of a line in point - slope form is given as ;
y -
= m (x -
)
= 4
= -2
m = 
Substitute the values into the equation , we have
y - (-2) =
( x - 4 )
y + 2 =
( x - 4 )
Which could be written as :
y + 2 = y + 2 =
x + 2
