Answer:

w = 9.82

x = 66.73

Step-by-step explanation:

By applying tangent rule in triangle ABD,

tan(81°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

6.31 = $\frac{62}{w}$

w = $\frac{62}{6.31}$

w = 9.82

Similarly,

tan(39°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

0.81 = $\frac{62}{(x+w)}$

0.81 = $\frac{62}{9.83+x}$

9.82 + x = $\frac{62}{0.81}$

x = 76.56 - 9.82

x = 66.74
