Web27 apr. 2024 · Triangles ΔABC and ΔDEC are similar trianglesbecause all three of their corresponding angles are congruent. Therefore, the ratios of their corresponding sides are equal. AB DE = BC EC. AB 6 = BC 10. Let's solve for BC: BC = 10 6 (AB) = 5 3 (AB) BC = 25 ft. (shadow of the building) Let's plug it in: 25 = 5 3(AB) WebBecause the slanty lines are assumed to be at the same angle from the horizontal, then these two triangles must be similar. Then we can use what you know about proportions and similar figures to solve the exercise.. Note that, because the height-lines and the ground are (assumed to be) perpendicular, the similar triangles are also right-angled … Web3 mrt. 2015 · This video shows how to calculate the height of a flagpole by using its shadow length and similar triangles. bulk sms software for windows 7
