Question

in triangle ABC a= 40 b=55 then c= wht

Answer 1

Given, A°=40°

B°=55°

Let the unknown angle be x

A°+B°+C°=180° (Angle sum property)

40°+55°+x=180°

95°+x=180°

x=180°-95°

x=85°

Therefore, A°=40°

B°=55°

C°=85°

Answer 2

Answer:

if a=40 ,b=55

c is =??

so 180-a+b=60

40+55=95

180-95=85

so c =85
