Answer:
Y=45x
Step-by-step explanation:
Y = f(x)
If you plot a chart, you can find that relation is just a linear relation. So y = mx + c
By putting any one case into the equation, you can find c = 0 and m = 45
Retest the equation for other cases to ensure u are correct
The complete question in the attached figure
we know that
<span>m∠BAC = 50°
</span><span>m∠CBA = 70°
and
</span>m∠BAC+m∠CBA+m∠ACB=180°
then
m∠ACB=180-[m∠BAC+m∠CBA]---------> 180°-[50°+70°]=60°
m∠ACB=60°
remember that
BC║DE
therefore
m∠ACB=m∠DEC
m∠DEC=60°
the answer is m∠DEC=60°
2. Is a Function and oof kinda forgot the rest sorry
