Answer:

  82°

Step-by-step explanation:

You are given two sides and the angle opposite one of them. This is sufficient information to make use of the Law of Sines to solve the triangle.

The angle (C) opposite the 89 m side can be found from the proportion ...

  sin(C)/89 = sin(30°)/48 . . . . . law of sines applied to the given information

Multiplying by 89 and taking the inverse sine, we have ...

  C = arcsin(89/48·sin(30°)) ≈ 67.98°

Then the unknown marked angle (E) between the sides is found using the fact that the sum of angles of a triangle is 180°.

  30° + E + C = 180°

  E = 150° -C ≈ 82.02° . . . . . . subtract 30°+C from both sides, substitute for C

Rounded to the nearest degree, the angle Devora turned was 82°.

_____

We have chosen to use the letter C to represent the angle at the Cave entrance; and the letter E to represent the angle at the Empty treasure chest.

The value we chose for angle C is the acute angle in accordance with the problem statement. There is another solution to the triangle in which this angle is the obtuse angle 112.02° = 180° - 67.98°.

The perimeter of a rectangular fence is to be at least 120 feet and no more than 168 feet. If the length of the fence is to be t
Shkiper50 [21]
A rectangle has a perimeter of length + length + width + width.

L = length of the fence.

W = width of the fence.

so the perimeter will be L+L+W+W or 2L+2W or 2(L+W).

now, we know that 120 ⩽ 2(L+W).

we also know that 168 ⩾ 2(L+W)

and we also know that whatever the length is, is twice the width, or L = 2W.

\bf 120\le 2(L+W)\implies 120\le 2(2W+W)\implies 120\le 2(3W)&#10;\\\\\\&#10;120\le 6W\implies \cfrac{120}{6}\le W\implies \boxed{20\le W}\\\\&#10;-------------------------------\\\\&#10;168\ge 2(L+W)\implies 168\ge 2(2W+W)\implies 168\ge 2(3W)&#10;\\\\\\&#10;168\ge 6W\implies \cfrac{168}{6}\ge W\implies \boxed{28\ge W}\\\\&#10;-------------------------------\\\\&#10;20\le W \le 28
