Question

How do you solve the right triangle given a=3.5cm, b=1.1 cm, C=90 degrees?

Answer 1

`c=3.669`, `/_A= 72.54^o` and `/_B=17.46^o`

Explanation:

As `/_C=90^o`, `a=3.5` and `b=1.1` (in cm.) are two sides of the triangle and third side hypotenuse is given by

`c=sqrt(3.5^2+1.1^2)=sqrt(12.25+1.21)=sqrt13.46=3.669`

Hence `sinA=3.5/3.669=0.95394` and `/_A= 72.54^o`

and `/_B=90^o-72.54^o=17.46^o`
