the angle of elevation of allied building is measured to be 2.34. after moving 1.6 km closer, it is found to be 4.62. find the height of the building.

Sagot :

[tex]tan4.62 = \frac{height}{x}[/tex]

[tex]tan2.34= \frac{height}{x+1.6}[/tex]

[tex]xtan4.62 = tan2.34(1.6+x)[/tex]

[tex]x = \frac{1.6tan2.34}{tan4.62 - tan2.34}[/tex]

just input it in your calculator:)
