Answer:

x = 622 (rounded to the nearest whole number value)

Step-by-step explanation:

=> Step 1: Solve for the base of top triangle;

Tan(39) = [tex]\frac{base1}{521}[/tex]

Tan(39) * 521 = base1

421.897 = base1

=> Step 2: Solve for the base of the bottom triangle;

Tan(21) = [tex]\frac{Base2}{521}[/tex]

Tan(21) * 521 = Base2

199.993 = Base2

=> Step 3: Finding x;

Base1 + Base2 = x

421.897 + 199.993 = x

621.89 or 622 = x

Hope this helps!
