A scalene triangle ______ has symmetry with respect to a line containing a median of the triangle.

Maru [420]

Hey there!

The definition of a scalene triangle is a triangle that has no equal sides, meaning that there cannot be a line of symmetry. A line of symmetry would be contained in a triangle that's an equilateral triangle, for example, which has three even sides. But since there are no even sides, there's no way for the triangle to be split in half evenly.

Your answer will be "never."

Hope this helped you out! :-)

A helicopter flying 3590 feet above ground spots the top of a 150-foot y'all cell phone tower at an angle of depression of 77° h

erik [133]

Answer:

794.19 feet.

Step-by-step explanation:

Please find the attachment.

Let x be the distance helicopter needs to fly to be directly over the tower.

We have been given that a helicopter flying 3590 feet above ground spots the top of a 150-foot y'all cell phone tower at an angle of depression of 77°.

We can see from our attachment that helicopter, tower and angle of depression forms a right triangle.

As height of tower is 150 feet, so the vertical distance between helicopter and tower will be $3590-150=3440$ feet.

We cab see from our attachment that the side with length 3590-150 feet is opposite and side x is adjacent side to 77 degree angle.

Since we know that tangent relates the opposite side of a right triangle to its adjacent side, so we will use tangent to find the length of x.

$\text{Tan}=\frac{\text{Opposite}}{\text{Adjacent}}$

Upon substituting our given values in above formula we will get,

$\text{Tan}(77^o)=\frac{3590-150}{x}$

$\text{Tan}(77^o)=\frac{3440}{x}$

$x=\frac{3440}{\text{Tan}(77^o)}$

$x=\frac{3440}{4.331475874284}$

$x=794.1865\approx 794.19$

Therefore, the helicopter must fly approximately 794.19 feet to be directly over the tower.

What the circumstances of a circle with a diameter of 12ft

Andrei [34K]

Circumstances?
I have seen a circle about that size used for a labyrinth at a church.

Circumference is found by multiplying the diameter by pi.
(12 ft)*π ≈ 37.7 ft
