98/2 = 49
Therefore,
49*2 = 98
Final answer: 49 times 2 equals 98
Answer: you use desmos. It’s helpful
Good luck !
Let's say x is longest side, y is shortest side and z is the other side. So we have some equations such that

(by the first sentence)

(by the second sentence)

(by the third sentence)
By the second equation, we have

and if we use it in the first equation, then

. So

Since

, if we use it in the third equation the we have

then

Therefore
Answer:
See below
Step-by-step explanation:
It has something to do with the<em> </em><u><em>Weierstrass substitution</em></u>, where we have

First, consider the double angle formula for tangent:

Therefore,

Once the double angle identity for sine is

we know
, but sure, we can derive this formula considering the double angle identity

Recall

Thus,
Similarly for cosine, consider the double angle identity
Thus,

Hence, we showed
