Assume that all triangles have interior angles less than 90°.A surveyor sights on a survey marker that is 132.3m distant. She ne

Vadim26 [7]

Answer:

85.9 m

Step-by-step explanation:

The law of sines can help figure this.

The remaining angle in the triangle is ...

180° -75° -68° = 37°

This is the angle opposite the leg from the surveyor to the second marker. Referencing the attachment, we have ...

b/sin(B) = c/sin(C)

b = sin(B)·c/sin(C) = 132.3·sin(37°)/sin(68°) ≈ 85.873 . . . meters

The surveyor is about 85.9 meters from the second marker.

Find the slope of the line passing through the points (2,-9) and )1,-3)

nignag [31]

Hi there!

$\large\boxed{\text{slope =} 6}$

We can calculate slope using the following formula:

$slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Plug in the corresponding points:

$slope = \frac{-9-(-3)}{2-1}$

Simplify:

$slope = \frac{-6}{1} = -6$
