Answer:
x = 15
Step-by-step explanation:
Assuming 3x and x-60 are in degrees, you can use:
cos(a) = sin(a+90)
To rewrite the equation as:
sin(3x) = sin(x-60+90)
sin(3x) = sin(x+30)
3x = x+30
2x = 30
x = 15
But, solving 3x = x+30 which simplifies to x=15 is not the only solution to this equation, as you can see in below picture. Finding all solutions is a bit more work, but maybe that is not required in your case.
Count the amount of 1 bag then you know one bag. The same amount has to be in each bag. So just multiply it by 3. The answer per bag is 10 so there are 30 blocks
Answer:
91
Step-by-step explanation:-5, 1, 7, 13
the common diference is : d = ( 13)-(7)=(7)-(1)=(1)-(-5)=6
the firt term is A1 = -5
the n-ieme term is : An = A1 +(n-1)d
An = -5+6(n-1)
An = 6n-11
the 17th term in the arithmetic sequence is : A17 = 6(17)-11 =91
