King Kong stands on the edge of the roof of a 62 foot high building. You poke your head out of a manhole and measure the angles

Oliga [24]

Answer:

46.55 feet (approx).

4.48 feet ( approx )

Step-by-step explanation:

Let x be distance manhole from the building. ( in feet ) and y be the height of the King Kong.

∵ The angles of elevation to the top of King Kong's head and to his feet are 55 degrees and 53.1 degrees respectively.

By the trigonometric ratio,

$\tan 53.1^{\circ}=\frac{62}{y}$

$\implies y =\frac{62}{\tan 53.1^{\circ}}\approx 46.55$

Thus, the distance of the manhole from the building would be 46.55 feet (approx).

Again by the trigonometric ratio,

$\tan 55^{\circ}=\frac{62+x}{46.55}$

$\tan 55^{\circ}\times 46.55=62 + x$

$66.48 = 62 + x$

$\implies x = 66.48 - 62 = 4.48$

Hence, King Kong is approximately 4.48 feet long.

Alvin’s first step in solving the given system of equations is to multiply the first equation by 2 and the second equation by –3

Ksivusya [100]

Answer:

One solution: 0x + 0.5y = 0

Step-by-step explanation:

9x + 4y = 36

6x + 2.5y = 24

2 * Eq. 1

18x + 8y = 72

-3 * Eq. 2

-18x - 7.5y = -72

Add the multiples of the equations.

0x + 0.5y = 0

Answer: One solution: 0x + 0.5y = 0
