8. Solve the following triangle for all missing sides and angles. Part 1: Find the measure of angle B

Part 2: Use the law of sines to find the length of side A

Part 3: Use any method to find the length of side c

Parte1 :

∡B= 180 - (42 + 83)= 55°

Parte2 :

Using the law of sines : ⇔ ⇔ a= 142.95

Parte3 :

Using the same law :  or    ⇔ c= 212.04

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
