Elevación de una cometa Un hombre que está en una playa hace volar una cometa. Sostiene el extremo de la cuerda
de la cometa al nivel del suelo y estima que el ángulo de eleva-
ción de la cometa es de 50°. Si la cuerda es de 450 pies de
largo, ja qué altura está la cometa sobre el suelo?

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
