Question

the base BC of triangle ABC is produce both ways and the measure of exterior angles formed are 94 degree and 126 degree. then find angle BAC. ​

Answer 1

Answer:

Use linear pair

The angles will be 180-94= 86 degrees

180-126 = 54 degrees

Then by angle sum property of a triangle

Third angle that is angle BAC will be

180- (54 + 86)

=> BAC = 180-140 = 40 degrees
