One of the legs of a right angled triangle is 100 m long If

One of the legs of a right angled triangle is 100 m long. If the angle opposite to this leg is 20 degrees, calculate the hypothenus.

Solution

According to given datas

opposite side=100

angle =20

sin20 = opposite/hypotenuse

sin20 = 100/hypotenuse

hypotenuse = 100/sin20

=292.4 m answer
