Triangle SAS

Calculate the triangle area and perimeter, if the two sides are 51 cm and 110 cm long and angle them clamped is 130 °.

Correct answer:

perimeter:  309.03 cm
triangle area:  2148.75 cm2

Step-by-step explanation:


Try calculation via our triangle calculator.

 v=110sin(130)=84.26 cm a2=51110cos(130)=121.71 cm c=v2+a22=148.03 cm  S=51v2=2148.75 cm2  p=a+b+c=309.03 cm
