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.

If the points A(2,a) and B(5,8) determine a line with a slope 2/3, find the value of a.

icang [17]

Answer:

(2,1) and "a" will be 1.

Step-by-step explanation: When you plot point B in a grid, use the slope to go up and down then find a place when x is 2. Then find the y and then you;ll have the answer.
