Answer:
4.2
Step-by-step explanation:
Step-by-step explanation:
x cos θ + y sin θ = x cos β + y sin β
<em>Let's say x = cos A, and y = sin A.</em>
cos A cos θ + sin A sin θ = cos A cos β + sin A sin β
<em>Use angle sum formula.</em>
cos(A − θ) = cos(A − β)
A − θ = ±(A − β)
A − θ = β − A
2A = θ + β
A = (θ + β) / 2
cot A = cot((θ + β) / 2)
x/y = cot((θ + β) / 2)
Well just how many times. That doesn't make much sense
Answer:
6:3
Step-by-step explanation:
all others are a ratio of 3:1 when you simplify it except 6:3 which is 2:1 when simplified
