Triangle side calculation

Calculate the lengths of the remaining sides of right triangle ABC, given angle alpha = 45° and perimeter o = 125.

Final Answer:

a =  36.6117
b =  36.6117
c =  51.7767

Step-by-step explanation:

α=45  o=125  β=90α=9045=45  α = β  o = a+b+c  sin α = a:c sin β = a:c  c sinα+c sinβ+c=o=125  c=1+sinβ+sinαo=1+sin45° +sin45° o=1+sin45° +sin45° 125=1+0.707107+0.707107125=51.7767  a=c sinα=c sin45° =51.7767 sin45° =51.7767 0.707107=36.612=36.6117
b=c sinβ=c sin45° =51.7767 sin45° =51.7767 0.707107=36.612=36.6117
