The angle of depression from the top of a building of a height 60metre of a stationary car is620 .find the distance between the car and the top of the building.

I do not know do you know

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)
