The answer is b) Mia is closer because her distance to the chest is opposite the smaller angle.

In the relationship of triangle sides and its angles, the shortest side will always be opposite to the smallest interior angle. Furthermore, the largest side will always be opposite to the largest interior angle. Since Mia's distance to the treasure chest is opposite to the smaller angle 65°, then she is much closer to the chest.

(1) To find the angle between v and positive x-axis, we first determine the angle formed by v and the negative x-axis. Since v = (-7,8), its vertical measure y is 8 units and horizontal measure x is 7 units.

arctan(8/7) = 48.81°

Solving for angle between v and positive x-axis:

180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ

Calculating for the dot product of the vector:

v1 x v2 = -7*1 + 8*0 = -7

Calculating vector magnitude:

|v1| = √(-7²+8²) = √113

|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

arctan(8/7) = 48.81°

Solving for angle between v and positive x-axis:

180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ

Calculating for the dot product of the vector:

v1 x v2 = -7*1 + 8*0 = -7

Calculating vector magnitude:

|v1| = √(-7²+8²) = √113

|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

The area is 38 because whenever you have to find the area in an equation you always add up the total sides. The shape is a rectangle and the only numbers they give is 6 and 13 obviously the sides are equal so the opposite side of 13 is 13 and the opposite side of 6 is 6 because they're both a certain length. In total you add up all the sides 13 plus 13 is 26, 6 plus 6 is 12 , 26 plus 12 is 38

The perimeter is 78 because they only give you two number so whenever you do a perimeter in an equation you always have to remember to multiply. 13 multiplied by 6 is 78. Hope this helped ( :

If A(x', y') & B(x",y") the the distance AB is given by the following formula:

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

Choice A. Work done below:

4x-1=5x-8 ( Set the opposite sides equal to each other).

4x-5x-1=-8 (Subtract 5x on both sides)

-x-1=-8 (Combine like terms)

-x=-8+1( Add 1 on both sides)

-x=-7 (Now since you have a negative sign on both sides you can cancel them)

x=7 ( Making that as your answer!!)

4x-1=5x-8 ( Set the opposite sides equal to each other).

**Answer:**

Height of the dam is 45.45 meters.

**Step-by-step explanation:**

From the attached figure, AB is the height of dam NM is Scarlett's height. We have to find the height of the dam. NM = CB = 1.65 m

Using trigonometric equations as:

**AC = 43.8 m**

**So, the height of the dam is AC + CB = 43.8 m + 1.65 m = 45.45 m**

**Hence, the height of the dam is 45.45 meter.**
