Pleaseeeee help me. i really need it.
deff fn [24]

comparing the relation given

thus y= -2x +1 to the general equation of a line

where y= mx + c

where m is the gradient and c is the intercept on the y-axis.

from the question, the gradient is -2 and since the line is perpendicular, the gradient is given as

\frac{ - 1}{m}

so substituting the value of m in to the equation

\frac{ - 1}{ - 2}

=

\frac{1}{2}

as the gradient

equation of line is given by

y - y1 = m( x-x1)

from the question y1= -2 and x1=1

substitute them

y-(-2) = 1/2 (x -1)

y+2 =1/2 (x-1)

multiplying through by 2

2 (y+2) = x-1

2y +4 = x-1

2y =x-1-4

2y =x-5

x -2y -5 = 0

therefore the equation for the line is x-2y -5=0

What are the missing sides and angles of this triangle? What is the area?
Butoxors [25]
This does not appear to be a right triangle.  However, we know 2 sides and the included angle, so can find the unknown side length.  Let x represent this length.  Then:

x^2 = (9 m)^2 + (12 m)^2 - 2(9m)(12 m)*cos 30 degrees, or

x^2 = 81 + 144 - 216(sqrt(3) / 2).  Please solve for x^2 and then solve the result for x, making sure to choose the positive value.  The result will be the length of the side opposite the 30 degree angle.

With 1 of 3 angles known, and 3 of 3 sides known, you can use the Law of Sines to find the other two angles.  As a reminder, the Law of Sines looks like this:

   a            b              c
-------- = --------- = ----------
sin A       sin B       sin C.

You can give the 30-deg angle any name you want; then a, the length of the side opposite the 30-deg angle, which you have just found.  And so on.
