The Red Line in the figure is an altitude of triangle hjl. Using right angle trig and properties of equality, y sin L = x = z sin H, write the Law of Sines for this triangle

Step-by-step explanation:

Simplifying the expression.

Multiplying both sides by x.

d

Step-by-step explanation:

The law of Sines applied to a Δ ABC is

= =

Using this in Δ HJL

= → (b)

Which may be expressed in reciprocal form as

= → (a)

Thus the law of Sines can be expressed as either (a) or (b)

answer: a.   one is a factor of every whole number since every number is divisible by itself.

b.an increase in a causes b to decrease
