Please help me solve this the way my professor did. Please show all work and formulas

Problem 6: A certain telescope has an objective of focal length f:=1500-cm. The Moon is used as an object , an image is formed with a height of h:=1.0-cm by the objective lens. What distance (relative height) corresponds to this image on the surface of the moon. object image 10 $1.0 cm 3.8 x 10 m h O := =0.038 deg 0= (6.667 - 10 ) rad moon :=3.8- 10 .m W= dom .0= (2.533 - 105) m think s= RO or tan (0)
