And the sum of both the sides on the same of the transversal is 180°
So,
Let angle 5 be x°
<h3>According to the question</h3>So Angle 5 = 129°

Answer:
The dimensions of the playground that will enclose the greatest total area are 140 ft x 210 ft.
Step-by-step explanation:
We have a rectangular with sides "a" and "b", so that the area is:
The perimiter for this rectangle is
The fence is for the perimeter plus the division, which has a length of "a".
So the total fencing is:
We can express one side in function of the other, in order to optimize the area.
Then, we can write the area as:
To maximize the area we will derive and equal to zero
Then, the value for the other side of the rectangle is:
Answer:
0,24 m
Step-by-step explanation:
La table est un rectanble donc l'angle en haut à droite est de 90°.
Tu connais donc un angle et le côté opposé à l'angle et tu cherche le côté adjacent.
On sait que tan(â) = donc :
tan(40)=
donc x ≈ 1,51 m
Le trou du mileu est à soit 1,27m du bord.
Donc elle doit taper à 1,51 - 1,27 = 0,24m du trou du milieu.
j'espère avoir été clair.
