He can go 1 1/2 days before they are all gone
Answer:
= x(a+b)(a-b) . x(b+c)(b-c) .x(c+a)(c-a)
just follow the steps given in the question
Angles of the parallelogram which is given in the problem are:α = 49° + 17 °= 66°
β = 180° - 66° = 114°
x - length of the longest side of the parallelogram;
Use the Sine Law:x / sin 49° = 20/ sin 17°
x / 0.7547 = 20 / 0.2924
0.2924 x = 15.094
x = 15.094 : .2924
x = 51.62 is the longest side of the parallelogram.
