40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
Answer:
Actually,I don't understand the que but I will try.
Step-by-step explanation:
Supplementry it means the pair of angle that sum if 180° similarly, complimentry angle sum is 90°
I assume your "reasons" mean "roots" or "zeros"
if 3 is a root, plug x=3 in the equation, you can find n:
3²+(n-1)*3+6=0
3(n-1)=-15
n-1=-5
n=-4
Plug n=-4 in the original equation: x²-5x+6=0
factor: (x-3)(x-2)=0
x=3, which we already know
or x=2, which is the value of m+4
m+4=2
m=-2
Answer:
y=4x-14
Step-by-step explanation:
m=(10-2)/(6-4)
m=8/2
m=4
y-y1=m(x-x1)
y-2=4(x-4)
y=4x-16+2
y=4x-14
