Use the formula for area!

I would assume it's the area of both the sidewalk and pool combined (79ft x 49ft = 3,871) minus the area of the pool alone (75ft x 45ft = 3,375). The area of the sidewalk would then be 496 ftx^{2}.

True or false Exterior angles are the angles created when the sides of the triangle are shortened.
Naddika [18.5K]

Answer:

The statement is false. Exterior angles are the angles created when the sides of the triangle are extended

Step-by-step explanation:

In order to find the exterior angle of a polygon, the side of the polygon is extended to go past the vertex of the polygon to form an angle adjacent and supplementary to the the interior angle of the polygon at the vertex of the polygon where the exterior angle is formed.

The sum of the exterior angle and the adjacent interior angle is equal to 180°

The exterior angle can also be described as being formed by one side of a polygon and an extension of the adjacent side to previous side of the same polygon and it can also be referred to as a turning or an external angle.

La Biblia dice que Matusalén vivió 979 años, mientras que Abraham vivió 175 años, escribe la fracción que indica la relación de
LenKa [72]

Answer:

A 175/979 = M

Step-by-step explanation:

Si Matusalén vivió 979 años y Abraham vivió 175 esto quiere decir que abraham vivio menos años que Matusalén.

Por lo que la fracción va a tener que ser menor que 1 ya que al multiplicarla por la edad de Matusalén nos tiene que dar la de Abraham.

Tenemos que encontrar una fraccion que multiplicada por 979 nos de 175.

979 * X = 175

Tenemos que despejar la x y encontraremos el valor de la fraccion.

979 * X = 175

X = 175/979

Nos fijamos si se puede simplificar, no se puede asique este es el resultado final.
