Question

The first one iswhat angle does a 3.8m ladder make with the ground, if it reaches 2.1m up the wall?

The second one is A concreter uses a ramp to wheelbarrow in sand from the ground level to floor level inside a building under construction. Floor level is 75cm above ground level. if the ramp is 5.4 m long what angle, to the nearest degree, does the ramp make with the ground level?
sin theta = 2.1/3.8 = opposite/hypotenuse
================================

same thing
sin theta = 0.75/5.4
