2. A surveyor uses a transit instrument that is 1.4 m off of the ground to measure the height of a hill that is along a planned path of a road. She measures the angle of elevation to the top of the hill to be 5.7°. She knows that the horizontal distance to the top of the hill is 775 m. How high does the current road surface need to climb to reach the top of the hill?
