Answer:
Pythagoras Theorem
Step-by-step explanation:
For any triangle ABC, the law of cosine is given by
Now, let us suppose the triangle ABC is a right triangle having right angle at C.
Thus, C = 90°
Substituting this value in above formula
We know that cos 90°= 0
Thus, the equation becomes
We can see that it reduces to Pythagoras Theorem.
Hence, we can conclude that law of cosines reduce to Pythagoras Theorem when dealing with a right triangle

Answer:
The area of the parallelogram is 40.
Step-by-step explanation:
You multiply the base by the height:
4*10= 40
Step-by-step explanation:
Let the total number of students in the choir be x
24℅ of x = 12
24/100 of x = 12
6x/25 = 12
6x = 12× 25
6x = 300
x = 50
