Step-by-step explanation:

A flagpole is 53 feet tall. Most of the time, this will be a vertical side of the triangle.

The flagpole and the ground are perpendicular to each other so they should form the legs of the triangles, this the triangle will be a right angle.

The rope will be the hypotenuse, the side opposite of the right angle.

Let the angle be y;
Then the supplement is 5y
y+5y=180
6y=180
y=30
The angle is 30 degrees

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:

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

0.8/y =2: 3/4 Please help

bulgar [2K]

Answer:

0.3

Step-by-step explanation:

0.8/y = 2 : 3/4

The value of y in the above expression can be obtained as follow:

0.8/y = 2 : 3/4

0.8/y = 2 ÷ 3/4

0.8/y = 2 × 4/3

0.8/y = 8/3

Cross multiply

0.8 × 3 = y × 8

2.4 = 8y

Divide both side by the coefficient of y i.e 8

y = 2.4/8

y = 0.3

Thus, the value of y is 0.3
