Its true you are doing it to both side. If you only one side, then the inequality would not be true. Subtract is like adding the negative . number, so you still would have to do it to both side of the inequality so the inequality is true,
Answer:
4.089
Step-by-step explanation:
24 degree is the Angle of elevation. SO we can use in this triangle Tan.
So tan 24 = AB/BC because tan is the ratio of height over adjacent.
So we can say it is tan 24 = (1.82)/BC
So BC = (1.82)/tan(24) = 4.089m
BC is representing shadow of men. So shadow of men is 4.089m

3/8=x/20
Multiply both sides by 20.
20(3/8) = 60/8 = 15/2 = 7.5
7.5 = x
