Answer:
3.2 feet
Step-by-step explanation:
The equation 
shows the height of water [
] and horizontal distance [
].
<em>Given the </em><em>horizontal distance is 4 feet</em><em>, they want to know the height.</em>
<em>Simply put 4 in of the equation and solve for . So,</em>
<em>
</em>
So, the height of the water was 3.2 feet above the ground.
So you would have -20C. Then you would multiply that by 1.8 which would give you -36 then you would add 32 which gives you your final answer which is -4 F
