this question is very simple. you apply, SOH CAH TOA formular. and then, the formular felts the question is TOA. so therefor, tan78=x/6. hence, make x the subject of the formular. x=6tan78. =6*4.7046=28.2278_to the nearest whole number we have=282m

In the question ,the distance from the top of the tree to the ground was stated to be 6cm.
but during the calculations it changed to 60cm why is that?
