hello fellas ... please help me with this,a farmer cooperator in an agricultural research wishes to fence the field in the form of right triangle. if one angle is 30° and the hypotenuse is 100m. find the cost of the fencing of the field if each meter of fencing materials costs him 80pesos ...

Answer 1

sketch the triangle. You know immediately the side opposite the 30 degree angle is 50m, and the third side is sqrt(100^2-50^2)...solve that.

cost=80*sum of three sides.
