It's so hard
for the first point you have
tan(60) = height/adjacent
for the second point you have
tan(45) = (height - 10m)/adjacent
so height/tan(60) = (height - 10m)/tan(45)
put in the values for each tangent and solve for height
tan(60) = height/adjacent
for the second point you have
tan(45) = (height - 10m)/adjacent
so height/tan(60) = (height - 10m)/tan(45)
put in the values for each tangent and solve for height
