Distance from base = 305 / tan(29.5deg)
= 539 ft
The answer is 129.13 is your answer. Remember, t<span>he perimeter of the base is 4s since it is a square. There is no formula for a </span>surface area<span> of a non-regular </span>pyramid<span> since slant height is not defined. To </span>find<span> the </span>area<span>, </span>find<span> the </span>area<span> of each face and the </span>area<span> of the base and add them.</span>
Answer:
The height of the lighthouse is 
Step-by-step explanation:
Let
h -----> the height of the lighthouse
we know that
The tangent of angle of 68 degrees is equal to divide the height of the lighthouse by the horizontal distance from the buoy to the base of lighthouse
so

Solve for h

The area would be 132cm^2 (squared)
(9x4)x2+(7+8)x4 =132
The perimeter you just add everything up so it’s 65cm
15+13+4+7+9+4+13
Answer:
