The system that you describe is said to be statically indeterminate since, there are more than 2 wires (minimum required to support the cement bag with inclined support).
There are three unknowns in the system that is the tensile forces in the wires. You should use three equations as follows to solve this.
Formulate the three equations and solve the algebraic equation to get the tension in each wire.

The phenomenon you talk about is called "Refraction". You an find an explanation, with diagrams, in the Wikipedia article on "Refraction". Basically, the change of direction is related to the change in the speed of the wave.
it depends on the first two: angle3 = 180 - angle1 - angle2
The interior angles of a four-sided object always at to 360 degrees. Therefore, if you know the other three angles, the solution to the fourth angle is: Angle4 = 360 - (Angle1 + Angle2 + Angle3) or... Angle4 = 360 - Angle1 - Angle2 - Angle3
LET angle 1= 2xangle 2= x"find the value of x"angle1 + angle2 = 902x + x = 903x = 903X = 30"subtitute the X with the equation"angle1 = 2x2(30)60angle2 = 30
draw a triangle & its exterior angle on one side and name he exterior angle as4 and interior opp. angle as 1 and 2 and name the third angle as 3 now we know exterior angle is equal to the sum of interior opp. angle so,angle1+angle2=angle 4 we also know angle3+angle4=180(linear pair) NOW from this 2 equation angle1+angle2+angle3=180
Displacement factor is equal to the power factor for linear loads with sinusoidal voltages and currents.pf = cos (angle1 - angle2)
New answer: If you use this internet site www.answers.com and ask the same question you will get a good description there of complementary angles. This is one of the best internet sites to get help on just about anything. Another very good internet site, especially for help with school homework is https://www.cia.gov/library/publications/the-world-factbook/index.html Try it once, I'm sure you will like it. The two sites I have told you about will give much better information than the kind of reply given below, and you won't have to put up with any 'grief'. Good luck.. Aussiecliff ok now u have to be an expert at angles to know this answer.. obviously i know that answer..23 degrees in not alot like seriously.. anyway i need to go biii sorry maybee later but i dnt know cya layer alligators dnt 4get ur toilet papers how lame was that lol unknown name************
If one considers reflective indicies, if the reflective index of the second medium (n2) is larger than the first (n1), the ray bends towards the normal. This means that n2 > n1Since n is defined as c/v, we know that the speed of light is greater in the first medium. Thus, when light changes speed from fast to slow, it bends towards the normal.

Every substance has its own index of refraction. The index of refraction affects the speed of the light passing through it. Air has an index of refraction of about 1.00 whereas water has an index of refraction of about 1.33. a simple ratio formula can be used to determine the final speed of the light through the water. (Vi/Vf)=(Ni/Nf) where v is the speed of light and N is the index of refraction. The angle would also change. The path of the light would 'bend' toward the normal line which is an imaginary line that runs perpendicular to the line where the air meets the water. Equation to find angle is (N2/N1) = Sin(angle1)/Sin(angle2).
