Line RS bisects PQ at point R. Find RQ if PQ = 4 3/4

svetlana [45]

PQ is bisected by RS at R. It means that PRQ is a line segment with PR = RQ and each of half of PQ.

RQ = PQ/2 = 1/2 [ 4 3/4 ] = 1/2 * 19/4 = 19/8  = 2 3/4

A circle has a circumference of 45 cm. What is the BEST estimate of the circle’s diameter?

ch4aika [34]

Answer:

C) 15 cm is the best estimate.

Step-by-step explanation:

The exact answer is not there, so 15 is the best estimate.

You can use this equation to help you:

d=C/π

Where d is the diameter.

C is the circumference.

And the last one is Pi.

You know that C = 45, so divide that by Pi (3.14).

45/3.14159 = 14.32

The closest answer is 15.

Hope this helps! Have a great day!

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.
