Sun rays

If the sun's rays are at an angle 60° then famous Great Pyramid of Egypt (which is now high 137.3 meters) has 79.3 m long shadow. Calculate current height of neighboring chefren pyramid whose shadow is measured at the same time 78.8 m and the current height of the nearby Mikerinovi pyramid which at the same time throws a shadow 35.8 m long.

Correct answer:

a =  136.4343 m
b =  61.9841 m

Step-by-step explanation:

h=137.3 m s=79.3 m  k=h/s=137.3/79.3=13737931.7314  α=180/π arctan(h/s)=180/3.1416 arctan(137.3/79.3)59.9907 °  a=k 78.8=1.7314 78.8=136.4343 m
b=k 35.8=1.7314 35.8=61.9841 m
