Find the length x to the nearest whole number. x almostequalto (Round to the nearest whole number as needed.)

Solution

applying tan rule on upper triangle

tan 39 = h1 / 518

h1 = 518 * tan 39

h1 = 419.47

now applying tan rule on lower triangle

h2 = tan 29 * 518

h2 = 287.132

x = h1 + h2

x = 419.47 + 287.132

x = 707 ( approximately )
