I hope this helps you
x^2+2x+8=0
x^2+2x+1+7=0
(x+1)^2= -7
(x+1)^2= i^2.7
x+1= i.square root of 7
x=-1+ i.square root of 7
Answer:
Step-by-step explanation:
Use trigonometry
<u>Let the height of the cloud be x, then we have:</u>
- tan 35° = x/525
- x = 525 tan 35°
- x = 367.6 (rounded)
The height of the cloud layer is 367.6 m
The position of the 7 is in the ten thousandths place.
