To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.

tresset_1 [31]
1. You have that:
 
 - Each gallon of paint covers 400 ft²<span>.
 - One side of a wall must be painted and its dimensions are :is 8 meters tall and 40 meters long.
 
 1 ft=0.3048 m
 1 ft</span>²=(0.3048 m)²=0.09290 m²
 
 2. Each gallon of paint covers 400 ft<span>², then:
</span> 
 400 ft²x<span>0.09290=37.16 m</span>²
 
 3. The area of one side of the wall is:
 
 A=8 mx40 m
 A=320 m²
 
 4. Therefore, you have:
 
 1 gallon-----37.16 m²
             x-----320 m²
 
 x=320x1/37.16
 x=8.61 gallons
 x≈9 gallons
 
 The answer is: 9 gallons
