Question

In Δ ABC, ㄥA =70° ,∠B =50° then findㄥC=​

Answer 1

the ∆ABC=180°

sum of angles of triangle is 180°

A+B+C=180

70+50+x=180

120+x=180

x=180-120

x=60

the angle c is 60°

please mark as brainliest

Answer 2

Answer:

angle A + angle B+ angle C =180 degree ( angle sum property of a triangle )

therefore 70+50+ angle C =180 degree

angle C= 180-120

therefore angle C = 60 degree

Step-by-step explanation:

this is the correct
