The angles of elevation of the top of a cliff from two boats A and B on the same side of the cliff and on the same horizontal level with the foot of the cliff are 30°
and 50° respectively. If the distance from the foot of the cliff to boat B is 30 m,
find by scale drawing:
(a) the height of the cliff.
(b) the distance between A and B.​

Issof claims that the scale factor is 1/2. which statement about his claim is correct

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
