Answer:
Given: In triangle ABC , AD is drawn perpendicular to BC.
Since AD is drawn perpendicular to BC, it creates two right triangles: ADB and ADC.
Prove that: 
Pythagoras triangle for right angle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.
In a right angle triangle ADB;
[By Pythagoras theorem]
or
.......[1]
Now, in right angle triangle ADC;
[By Pythagoras theorem]
or we can write this as;
......[2]
Substituting the equation [1] in [2] we get;
hence proved!
Your answer will be negative 96
Its just showing a question and I don't know what to do
sinh(ln(4)) = (exp(ln(4)) - exp(-ln(4)))/2 = (4 - 1/4)/2 = 15/8 = 1.875
sinh(4) = (exp(4) - exp(-4))/2 ≈ 27.28992
Answer:
I think the answer is 613,280,000
