<h2>Solution:.</h2>

Let the ceilings be <em>a</em><em> </em><em>&</em><em> </em><em>b</em>

and the distance from one corner of the ceiling to the opposite be <em>c</em>

<em>then </em><em>using</em><em> </em><em>Pythagoras</em><em> theorem</em>

c =  \sqrt{a {}^{2} +  b  {}^{2} } \\  c =    \sqrt{16 {}^{2} +  12  {}^{2} } \\ c =  \sqrt{256 + 144 }  \\ c =  \sqrt{400}  \\ c = 20

hence ,c .°. the distance from one corner of the ceiling to the opposite is<em> </em><em>2</em><em>0</em>

Chords and arcs. Can someone please help me with this and explain???20 points
anyanavicka [17]

Answer:

89

Step-by-step explanation:

So the line segment CD is 12.7 and half that is 6.35.  I wanted this 6.35 so I can look at the right triangle there and find the angle there near the center.  This will only be half the answer.  So I will need to double that to find the measure of arc CD.  

Anyways looking at angle near center in the right triangle we have the opposite measurement, 6.35, given and the hypotenuse measurement, 9.06, given. So we will use sine.

sin(u)=6.35/9.06

u=arcsin(6.35/9.06)

u=44.5 degrees

u represented the angle inside that right triangle near the center.  

So to get angle COD we have to double that which is 89 degrees.  

So the arc measure of CD is 89.

The length and breadth of rectangular field are 240m and 200m respectively. Find the cost of digging the field at Rs 10 per m^2​
Inga [223]

Answer:

Please check the explanation.

Step-by-step explanation:

Given

  • The length of rectangular field = l = 240m
  • The breadth of rectangular field = w = 200m

We can determine the area of the rectangular field using the equation

A=wl

where

  • l is the length
  • w is the width

substituting  l = 240m, and  w = 200m in the formula

A=wl

A = 240 × 200

A = 48000 m²

Given that the cost of digging the field at Rs 10 per m².

Thus,

The cost of digging the field of the area 48000 m² = 10 × 48000

                                                                                     = 480000 Rs

Therefore, the total cost of digging = 480000 Rs

Jan's motorboat travels at a speed of 14 mph in still water. Booth river flows at a speed of 4 mph. How long will it take Jen to
Leya [2.2K]
Upstream: 14 - 4 = 10. Miles per hour.
16 miles = 1.6 hours.

Downstream: 14 + 4 = 18.
16 miles = 16/18 = 8/9 or 0.888 of an hour.
