Answer 2

Answer:

To find it first we need to find the angle ACB first

= (180°-130°) [180° because it forms a straight angle] = 50°.

therefore angle ACB is 50°.....

Now, to find angle BAC we have to add 50° and 60° and sub it from 180°

= (180°-{60°+50°}) [ 180° is the ang.sum.prop.of triangle]

= 180°-110°= 70°

so we can conclude that angle BAC is 70 and ACB is 50°.....

And to verify whether ans is correct we need to add all Angs of the triangle and see whether it is coming 180 deg or not

[60°+70°+50°] = 180°......

Therefore we can say the ans is correct.....
