Step-by-step explanation:
Imagine a right triangle where a and b are the legs and c is the hypothenuse.
Pitagora: a²+b²=c²
Divide by c
(a/c)²+(b/c)²=1
But a/c=sin(B) and b/c=cos(B)
Thus sin² + cos² = 1
Answer:
y=-2x-4
Step-by-step explanation:
When an equation is perpendicular, then it is the equation's inverse. The inverse of 1/2 is -2
