We want to write

$\frac{\sqrt[]{5}+1}{2}$

as decimal, doing it on a calculator we have

$\frac{\sqrt[]{5}+1}{2}=1.61803398875$

But we only need three decimal places, then the result is

$\frac{\sqrt[]{5}+1}{2}=1.618$

<h3>Answer:</h3>

$\boxed{\boxed{\pink{\bf \dag Value \ of \ x \ is \ 6\ and\ y \ is\ (-21) .}}}$

<h3>Step-by-step explanation:</h3>

In the Question , its given that ∆ART $\cong$ ∆ DFI . And we need to find the values of x and y . So we know that ,

If two triangles are congruent then their Corresponding angles and sides are equal.

Hence here in ∆ ART & ∆ DFI :-

AT = DI ( cpctc)
AR = DF ( cpctc)

$\bf\implies AT = DI \\\\\bf\implies 6x + 31 = 67 \\\\\bf\implies 6x = 67 - 31 \\\\\bf\implies 6x = 36 \\\\\bf\implies x =\dfrac{36}{6}\\\\\bf\implies \boxed{\red{\bf x = 6}}$

Hence the value of x is 6 .

$\rule{200}2$

$\bf\implies AR = DF \\\\\bf\implies -4y+19 = 103\\\\\bf\implies -4y = 103-19 \\\\\bf\implies -4y = 84 \\\\\bf\implies y =\dfrac{84}{-4}\\\\\bf\implies \boxed{\red{\bf y = -21}}$
