If the perimeter is 1,013 units, find the value of x and the area of the triangle

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
