justin built a skateboard ramp by elevating one end of an 8 foot piece of plywood so that it makes a 20° angle with the ground. approximately how high did justin elevate the raised end of the ramp?

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)
