30 feet by 14 feet just means 30x14 which is equal to 420 square feet if each piece is 1x1 then he will need 420 pieces of sod
Add 55kg and 52 kg and 53.2 kg and divide by 8 and that will give you your answer
In the triangle , Angle A is 51.1 degrees, B is 54.5 degrees , C is 74.4 degrees.
<h3>What is a Triangle ?</h3>
A triangle is defined as a polygon with three sides , three angles and three vertices.
Using the Law of Cosine to solve the Triangle and to determine the value of all the angles
c² = a²+ b² -2abCosC
a = 42 , b=44 , c = 52
52² = 42² + 44² -2 * 42 * 44 cos C
2704 = 1764 + 1936 -3696 cos C
cos C = 0.269
C =74.4 ° (degrees)
Similarly calculating for A and B will give
Angle A is 51.1 degrees
Angle B is 54.5 degrees
