First, let's label each coordinate of the points with x1, y1 and x2, y2

Our first point: (3, -1). 3 is x1 and -1 is y1

Our second point: (-10, 9). -10 is x2 and 9 is y2.

Slope = (y2 - y1) / (x2 - x1)

Let's plug our values into the slope formula above.

Slope = (9 - (-1)) / (-10 - 3) = 10/-13 or -10/13

Write and solve an equation to find the value of x and a missing angle in the triangle below.
Arturiano [62]

Answer:

x = 27°, ∠JLK = 55°

Step-by-step explanation:

From the diagram in the question above,

The exterior angle of a triangle is equal to the sum of the two opposite side

3x+13 = 39+(2x+1)

3x+13 = 40+2x

collect like terms and solve for x

3x-2x = 40-13

x = 27°.

∠JKL = 2x+1

Substitute the value of x

∠JKL = 2(27)+1

∠JKL = 54+1

∠JKL = 55°
