Answer:
the scale is 630:1 = 0.16%
80inch^2 of 50400inch^2 however = 0.16%
Step-by-step explanation:
350ft^2 = 50400inches 8 x 10 = 80inches = 50400/80 = 630
50400/9 =5600 we distribute
5600/80 = 7
showing us that 7 x 9 = 63 where 63 x 80 = 5040 1/100th
1 = 630
7x9x 80 = 1/100 of 50400
0.01589 x 7x9x80x 7x9x80 = 80
Proves that every every 10000 the percentage goes down 0.00011%
Step-by-step explanation:
This is known as the triple tangent identity. Start with the fact that the three angles add up to 0.
(x − y) + (z − x) + (y − z) = 0
Subtract two terms to the other side and take the tangent:
x − y = -((z − x) + (y − z))
tan(x − y) = tan(-((z − x) + (y − z)))
Use reflection property:
tan(x − y) = -tan((z − x) + (y − z))
Now use angle sum identity:
tan(x − y) = -[tan(z − x) + tan(y − z)] / [1 − tan(z − x) tan(y − z)]
tan(x − y) = [tan(z − x) + tan(y − z)] / [tan(z − x) tan(y − z) − 1]
tan(x − y) [tan(z − x) tan(y − z) − 1] = tan(z − x) + tan(y − z)
tan(x − y) tan(z − x) tan(y − z) − tan(x − y) = tan(z − x) + tan(y − z)
tan(x − y) tan(z − x) tan(y − z) = tan(x − y) + tan(z − x) + tan(y − z)
