$\cfrac{a}{sinA}= \cfrac{b}{sinB} \ \ \to \\ sinB= \cfrac{b*sinA}{a} = \cfrac{14*sin35^o}{12}= 0.6692 \ \ \to \ m \angle B=42^o \\ \\ \\ m \angle C=180- m \angle A- m \angle B=180-35-42=103^o \\ \\ \\ \cfrac{a}{sinA}= \cfrac{c}{sinC} \ \ \to \ c= \cfrac{a*sinC}{sinA}= \cfrac{12*sin103^o}{sin35^o} \approx 20.4$

A triangle has sides with links that are consecutive odds intergers .The perimeter of the triangle is a hunt is 144 cm what's th

Rasek [7]

Answer:

50cm

Step-by-step explanation:

If the sides are consecutive odd integers,

Let the smallest side=y

The other sides are y+2 and y+4

The perimeter=144cm

y+y+2+y+4=144

3y+6=144

3y=144-6

3y=138

y=138/3=46cm

Therefore, the largest side of the triangle:

y+4=46+4=50cm

Therefore, the largest side of the triangle is 50cm
