I assume that you mean the *numeral* 7, the written for of the number in a common font.
<span>This has no symmetry. In an extreme case, with the top extended to be the same length as the slant stroke, and restricting both to simple line segments, *then* you would have symmetry across a line bisecting the angle.</span>

A rectangle and an equilateral

jek_recluse [69]

Answer:

The area of the rectangle = 50 cm^2.

Step-by-step explanation:

Let the shortest side of the rectangle be x cm.

Perimeter of the rectangle is:

2x + 2(x + 5).

Perimeter of the triangle = 3 * 2x.

As they have the same perimeter:

2x + 2(x + 5) = 3*2x

2x + 2x + 10 = 6x

6x - 2x - 2x = 10

2x = 10

x = 5 cm.

So the area of the rectangle = x(x + 5)

= 5 * 10

= 50 cm^2.

What is 5 2/3 x 13? I'm not really good with fractions

Natasha2012 [34]

Answer:

The answer is 221/2 or 73 ⅔

Step-by-step explanation:

5 ⅔ = (3 × 5 + 2) ÷ 3 = 17/3

Now,

17/3 × 13 = 221/2 = 73 ⅔

Thus, The answer is 221/2 or 73 ⅔

A navigator plots the course a plane is currently traveling. The plane is 300 miles from its destination. If it continues on its

inna [77]

We have to use the rule of cosx° to solve this problem. Attached is a diagram of the navigator's course for the plane. It is similar to the shape of a triangle. We know the plane is 300 miles from its destination, so that will be one of the sides. On the current course, it is 325 miles from its destination, so that will be another one of the sides. The last side is 125 because that is the distance between the destination and the anticipated arrival. Cosx° is what we are looking for.

To find how many degrees off course the plane is, we must use the rules of Cosx°, which is shown in the attached image.

The plane is approximately 23° off course.
