Question

An exterior er angle of triangle is 118 degree. If one of two interior is 54 degree. Than others opposite angle is.

Answer 1

Answer:

118-54

=64 degree is the write answer

Answer 2

Answer:

Suppose triangle ABC and ADE is exterior angle

ABC= 54 and ADE= 118

ACB+ADE=180

ACB+118=180

ACB= 180-118= 62

BAC+ACB+ABC=180

BAC+62+54=180

BAC+116=180

BAC= 180-116 =64
