Answer:
c) $200
Step-by-step explanation:
if the farmer wishes to earn $1500 per year he needs 1500/75=20 trees producing fruit
Because each tree produces 75$ of fruit per year
if we wants 20 trees he has to spend 20*$10=$200
Because each tree has a cost of 10$
Answer:
AC = 12.5 cm
Step-by-step explanation:
use cosine law c^2 = a^2 + b^2 − 2ab cos(C)
c^2 = 6^2 + 10^2 - 2(6)(10)(cosin100)
c^2 = 156.84
c= √156.84
c= 12.5 cm
The cosine rule is used when we are given either three sides or two sides and the included angle.
