Find the area of △LKJ.

The correct answer is letter c.

Step-by-step explanation:

The area equation of a triangle is given by:

 (1)

Where:

b is the base

h is the height

Let's find first the angle MJK (α), using the tangent definition.

Now, if α = 37° then β (angle JLK) must be:

Now, we can find the distance ML using again the tangent definition:

The base of the triangle LKJ will be:

Therefore, using equation (1) the area of △LKJ will be:

The correct answer is c.

I hope it helps you!

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
