3/(5x) + x = 3/(5x) + x/1 * (5x)/(5x)
= 3/(5x) + 5x²/5x
= (3+5x²) / 5x

Let ∠1 be x

Let ∠2 be x-12

$\rm(x - 12 )+ x = 90 \degree$

$\rm2x - 12 = 90 \degree$

$\rm2x = 90 + 12$

$\rm2x = 102$

$\boxed{ \bf \: x = 51 \degree}$

$\sf \: ∠1 = x \\ \sf \: = 51 \degree$

$\sf \: ∠2 = x - 12 \\ \sf = \: 51 - 12 \\ \sf∠2 = 39 \degree$

Let x represent the percent of increase in the tree's height and let n represent the number of years.

x= n (36/4343)

Hope this helps!
