What does the and 2 mean? Does it mean times two or plus two?
Step-by-step explanation:
((1+4i)/i) +(1+i)/(2+5i)
(((1+4i)*(2+5i)) +((1+i)*<span>i))/(i*(2+5i))
</span>((2 + 8i + 5i +20i²) + (1i + i²) )/ (2i + 5i<span>²)
((2 + 13i -20) + (1i -1))/(2i - 5) where </span>i<span>² = -1</span><span>
((14i - 19) +0)/2i - 5
(14i -19)/(2i - 5) </span>
Sin(angle) = Opposite leg / Hypotenuse
Angle = 8 degrees
Opposite leg = 2.3 feet
Sin (8) = 2.3 ft. / Z
Z = 2.3 / sin(8)
Z = 16.5 feet
Answer:
Step-by-step explanation:
can be said as " divided by 
", so the ? is .
The original number is .9
