a school wants to build a rectangular playground that will have a diaonal length of 75 yards. how wide can the playground be if
adoni [48]
You would use the Pythagorean Theorem.
a2 + b2 = c2
302 + x2 = 752
900 + x2 = 5625
900 – 900 + x2 = 5625
X2 = 5625
√(x^2 ) = √5625
X = 75
It is 75 yards wide. I've included a drawing of the rectangle if it helps.

b) Sobreyectiva: es si todos los elementos del conjunto final tienen al menos una correspondencia del conjunto inicial

c) Biyectiva: es cuando la correspondencia es inyectiva y sobre inyectiva a la vez

Correspondencia unívoca : es una correspondencia donde cada elemento del conjunto origen se corresponde con solo un elemento del conjunto de llegada.

Alternate exterior angles are congruent.
Lemur [1.5K]

Answer:

<1 = <8

Step-by-step explanation:

An angle that will form a pair of alternate exterior angles with <1 will be the angle that is found outside of the parallel lines but on the opposite side of the transversal that cuts across the two parallel lines.

<8 is an exterior angle, and also is alternate angle to <1. It forms a pair of alternate exterior angles pair with <1.

Therefore, <1 = <8
