Given that a right angled triangle with bottom side of the triangle is 40cm and the there are 2 angles attached to it, 40degrees and 90degrees.

So adjacent w r to angle # 40^@# is #40# cm.

So #"opposite"/"adjacent"=tan40^@#

Hence #"opposite"=40*tan40^@=33.56# cm.

Again

#"hypotenuse"/"adjacent"=sec40^@#

So #"hypotenuse"=40*sec40^@=52.21#cm
