# Calculate triangle

In the triangle ABC, calculate the sizes of all heights, angles, perimeters and its area, if given a-40cm, b-57cm, c-59cm

o =  156 cm
S =  1087.4907 cm2
v1 =  54.3745 cm
v2 =  38.1576 cm
v3 =  36.8641 cm
A =  40.2961 °
B =  67.1615 °
C =  72.5424 °

### Step-by-step explanation:

$C=180-A-B=180-40.2961-67.1615=72.542{4}^{\circ }=7{2}^{\circ }3{2}^{\mathrm{\prime }}33\mathrm{"}$
