The question isn’t clear but If you’re talking about triangles then it would be an enlargement
Hi there!
We are given:
cos(7x)cos(4x) = -1 - sin(7x)sin(4x)
Begin by moving all terms with variables to one side:
cos(7x)cos(4x) + sin(7x)sin(4x) = -1
The corresponding trig identity is cos(A - B). Thus:
cos(7x - 4x) = cos(7x)cos(4x) + sin(7x)sin(4x) = -1
cos(3x) = -1
cos = -1 at π, so:
3x = π
x = π/3
We can also find another solution. Let 3π = -1:
3x = 3π
x = π
Thus, solutions on [0, 2π) are π/3 and π.
Answer:
1)49
2)231
Step-by-step explanation:
1)
4+9=13
4*2=8
8+1=9
2)
2+3+1=6
2+1=3
1*2=2
Answer:
not enough information given
Step-by-step explanation:
as the rules say, we need at least 3 pieces of information :
2 angles and a side, or 3 angles (or there are other options like 2 sides and one angle or 3 sides).
but here we get 1 side and 1 angle. the shared point does not give us anything in that regard.
so, not enough information.
