  • The angle between two adjacent vanes of a fan that has 6 vanes

<h3>What are acute angles?</h3>

As a general rule, an acute angle, x is represented as: x < 90

This means that acute angles are less than 90 degrees.

<h3>The real life scenarios</h3>

The real life scenarios that involve acute angles are scenarios that whose measure of angle is less than 90 degrees.

Sample of the real life scenarios that satisfy the above definition are:

  • Sighting a ball from the top of a building at an angle of 55 degrees.
  • The angle between two adjacent vanes of a fan that has 6 vanes

A rectangle has length (3x-8) and width (2x-7) cm .Write down and simplify an expression for the perimeter of the rectangle. So
tatuchka [14]

Answer:

The perimeter of the rectangle is equal to (10x-30)\ cm

Step-by-step explanation:

Let

L-----> the length of the rectangle

W ----> the width of the rectangle

we know that

The perimeter of rectangle is equal to

P=2(L+W)

we have

L=(3x-8)\ cm\\W=(2x-7)\ cm

substitute

P=2((3x-8)+(2x-7))

P=2(5x-15)

P=(10x-30)\ cm
