A lamppost cast a shadow of 12 ft when the angle of elevation of the Sun is 32.4º. How high is the lamppost? Round to the nearest foot.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
