The perimeter of a triangle is 170 feet and the sides are in the ratio 25: 14: 12. what is the area of the triangle

i think 170 squared= 28900

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,
