25 coins because 50+20+5 = 75. Then divide 75 by 3 = 25. Each bag has 25 coins.
Hope that helps!!
{tan(60) + tan(10)}/{1 - tan(60)*tan(10)} - {tan(60) - tan(10)}/{1 + tan(10)*tan(60)}
<span>ii) Taking LCM & simplifying with applying tan(60) = √3, the above simplifies to: </span>
<span>= 8*tan(10)/{1 - 3*tan²(10)} </span>
<span>iii) So tan(70) - tan(50) + tan(10) = 8*tan(10)/{1 - 3*tan²(10)} + tan(10) </span>
<span>= [8*tan(10) + tan(10) - 3*tan³(10)]/{1 - 3*tan²(10)} </span>
<span>= [9*tan(10) - 3*tan³(10)]/{1 - 3*tan²(10)} </span>
<span>= 3 [3*tan(10) - tan³(10)]/{1 - 3*tan²(10)} </span>
<span>= 3*tan(30) = 3*(1/√3) = √3 [Proved] </span>
<span>[Since tan(3A) = {3*tan(A) - tan³(A)}/{1 - 3*tan²(A)}, </span>
<span>{3*tan(10) - tan³(10)}/{1 - 3*tan²(10)} = tan(3*10) = tan(30)]</span>
Answer:
the sum is 48
Step-by-step explanation:
11 + 8 is equal to 19. When you add 29 to 19 the sum would be 48
Answer:
I really want to help you but I am really confused with those topics. I am very sorry.
Step-by-step explanation:
Answer:
y = -5
x = 2
Step-by-step explanation:
The computation is show below:
Given that
-6x - 6y = 18
6x - 3y = 27
Now if we solved both equation so
-9y = 45
y = -5
And, x is
-6x - 6(-5) = 18
-6x + 30 = 18
-6x = 18 - 30
-6x = -12
x = 2
