Solve the triangle.<br><br> B = 36°, a = 38, c = 18
Lady_Fox [76]
Solving the triangle requires solving all of the dimensions involve in the polygon given. We are given an angle, and two of the sides of the triangle. We can solve the third side by using the law of cosines.

b² = a²+c²-2accos(B)
b² = 38² + 18² - 2(38)(18)cos(36)
b = 25.7

We use the law of sines to solve for the angles.
a/sinA = b/sinB
38/sinA = 25.7/sin36
A = 60.4
°
C =
180 - 36 - 60.4 = 83.6°

Answer:

We can conclude that the distance from Sandy's Hotel to Trader Joes' Store is:

  • d = 8.06 miles

Step-by-step explanation:

From the coordinate plane, we can clearly identify that:

  • Sandy's Hotel is located at the point (-8, 9)
  • Trader Joes' Store is located at the point (-4, 2)

The distance from Sandy's Hotel to Trader Joes' Store can be calculated such as:

d=\:\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

The distance between (-8, 9) and (-4, 2)

d=\sqrt{\left(-4-\left(-8\right)\right)^2+\left(2-9\right)^2}

  =\sqrt{\left(-4+8\right)^2+\left(2-9\right)^2}

  =\sqrt{4^2+7^2}  

   =\sqrt{16+49}

    =\sqrt{65}

    =8.06 miles

Therefore, we can conclude that the distance from Sandy's Hotel to Trader Joes' Store is:

  • d = 8.06 miles
