Answer:

x = 18

Step-by-step explanation:

The given angle is a right-angled triangle.

Such triangles have an angle that equals 90°.

The square attached at the base represents 90°. [Whenever you such a square between two sides, simply put the angle between those sides equal to 90.]

So, the points we know about this triangle:

One angle is = 90
Another angle given in the question is 72°.

*Property*

The sum of all angles in a triangle = 180

==> 90 + 72 + x = 180

==> 162 + x = 180

==> x = 180 - 162

==> x = 18

The roof of the Terminal Tower is 709 feet above ground. A window washer dropped a bucket from the edge of the roof. How many se

Masja [62]

Answer:

6.64 seconds

Step-by-step explanation:

Given that:

Distance between roof of the terminal and ground = 709 feet

A bucket was dropped from the roof.

To find:

The time taken by the bucket to hit the ground?

Solution:

Distance traveled, $s$ = 709 feet

Initial velocity of the bucket, $u$ = 0 feet/sec (because initially it was at rest)

Acceleration of the bucket will be equal to acceleration due to gravity i.e.

$g$ or 32.1741 $ft/sec^{2}$

Let the time taken is $t$ seconds.

Formula for distance is given as:

$s = ut+\dfrac{1}{2}at^2$

Putting all the values:

$709 = 0 (t) + \dfrac{1}{2}(32.1741) t^2\\\Rightarrow 1418 = 32.1741 t^2\\\Rightarrow t^2 = 44.07\\\Rightarrow t \approx \bold{6.64\ sec}$

Leni [432]

The probability that a U.S. household selected at random has a computer and has Internet access will be 0.72. The C and I are independent events. Then the correct option is B.

<h3>What is probability?</h3>

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

Approximately 80% of households in the United States have computers. Of those 80%, 90% have Internet access.

Then the probability that a U.S. household selected at random has a computer and has Internet access will be

P(C and I) = 0.80 × 0.90

P(C and I) = 0.72

Then the C and I are independent events.

Then the correct option is B.
