Using the Law of Cosine formula, you can find the measurement of the third side of a scalene or isosceles triangle. 

C^2 = A^2 + B^2  -  2AB(cosC)

C^2 = 10^2 + 13^2  -  2(10)(13)(cos78degrees)
C^2 = 100 + 169  -  2(10)(13)(cos78degrees)
C^2 = 100 + 169  -  2(10)(13)(0.21)
C^2 = 100 + 169  -  54.06
C^2 = 269  -  54.06
C^2 = 214.94
C^2 = square root of 214.94
C = 14.66

The answer for this question would be 14.7 ft. :D

Find the area of triangle ABC when b= 141 degrees a= 7 and c=8
Vlad [161]
  You basically use the formula height*base/2 to find the area of the triangle. For instance, let's say a is your chosen base, which has a length of 7. You then use the pythagorean theorem of the right triangle (which is formed by splitting the triangle in half), which is a^2+b^2=c^2, and you substitute half your base for a and the other length (8) for c, which is the hypotenuse of the triangle. Note how this is all being done to find "b", which is the height of the triangle, which will then help you substitute all of your known values into the area formula of a triangle to answer your question. I'm not sure if b=141 degrees would have an impact on this question, but I hope this helped you in some way.

A vessel has 4 liters and 500 ml of curd. In how many glasses, each of 25 ml capacity, can it be filled?
dalvyx [7]

Step-by-step explanation:

easy to look up : mili stands for 1/1000

so,

500 ml are 500/1000 liters.

25 ml are 25/1000 liters (a tiny glass).

and 1 Iiter is of course, 1000/1000 liters (1000 ml).

4 liters 500 ml are then

4×1000/1000 + 500/1000 = 4500/1000 l = 4500 ml.

how many glasses of 25 ml can be filled with that ?

this is the same question as into how many parts of 25 can 4500 be split ? or, how often does 25 fit into 4500 ?

all this is done by division :

4500 / 25 = 180

so, 180 of such glasses can be filled.
