Explanation Given: The Santa Cruz light-house is 14 m tall and casts a shadow of 28 m long at 7 P .M . At the same time, the shadow of the lighthouse keeper is 3.5 m long. Formula used: Angle – Angle (AA) Similarity Property – If the measures of one triangle are equal to those of two corresponding angles of a second triangle, then the two triangles are similar. When two triangles are similar, then the ratio of the corresponding sides are equal. Calculation: Consider the triangle △ A B C in which A B is a Santa Cruz light-house and B C is the shadow of the lighthouse. At the same time, the shadow cast by lighthouse keeper is 3 .5 m long. So, again consider a triangle △ E F G in which E F is a lighthouse keeper and F G is the shadow cast by the lighthouse keeper. So, the figure of the triangle △ A B C and △ E F G is: In △ A B C and △ E F G , ∡ B = ∡ F Both angles ∡ B and ∡ F are 90 ° , because lighthouse and lighthouse keeper both are vertical to the ground
