Question

how to find the side of right angled tringle when two sides r given as:
base=30cm and
hypotenuse =45cm
one angle is 90 degree

Answer 1

Use Pythagoras Theorem-
square of hypotenuse= square of perpendicular + square of base
you get, square of perpendicular= square of hypotenuse - square of base
then solve by putting values, you will get answer.

Answer 2

by using Pythagoras theorem
base ^2 + perpendicular^2 = hypoteneous^2
put the given value in each .

note : opposite side of given angle ( 90) is hypteneous.
