12. A lighthouse is built on the edge of a cliff located near the ocean, as shown in the accompanying diagram. From a boat 200 feet from the base of the cliff, the angle of elevation to the top of the cliff is 18 degrees and the angle of elevation to the top of the lighthouse is 28 degrees . What the nearest foot? is the height of the lighthouse, x, to Cliff 200 ft A. 41 feet B. 65 feet C. 106 feet D. 221 feet

-81 -56 -27 0 81

step-by-step explanation:

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
