e=44.93

Answer 2

how did you get that @groges

Answer 3

First let me make sure is it a right angled triangle u tried to draw?

Answer 4

yes

Answer 5

Okay then use the rules of a right angles triangle, its easy. they are on p16 of my log tables.
anyway its cosA=b/c so its cos58=f/53 = 28.08

Answer 6

sin 58 degree is 0.848
and as we know sinA=height/hypotenuse,here it is e/53=sin 58
so e=0.848*53=44.94

Answer 7

and tan58=e/28.08 = 44.93

Answer 8

Ok I get it thanks :)
