Un pájaro vuela en línea recta desde la Copa de un árbol a la de otro árbol que está 2 metros más abajo, formando un ángulo de vuelo de 70° con la vertical. Sen70°=0.94 cos70°=0.34 Según valores aproximados de seno y de coseno, ¿que distancia volo el pajaro?

The bird flew 5.45m far from the tree.

Step-by-step explanation:

Given,

Sin70° = 0.94

Cos70° = 0.34

Angle of flight = 70°

Refer the diagram attached for better understanding.

Cos70° = (adjacent side) / (hypotenuse)

0.34 = 2/ hyp

hyp = 2/(0.34)

hyp = 5.8 m

We have to find the opposite side of the angle of flight for the distance the bird flew.

Sin70° = (opposite side) /(hypotenuse)

0.94 = (opposite side) / 5.8

Opposite side= 0.94 x 5.8

= 5.45m

The bird flew 5.45m away from the tree to another tree.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
