Question

b)Two angles of a triangle are of measure 80 degree

and 30degree

. Find the measure of third angle​

Answer 1

Answer:

70 degree

Step-by-step explanation:

Angle Sum Property of a Triangle states that Sum of all the angles of a Triangle is 180 degree

Therefore, [180-(80 + 30)]degree = [180 - 110] degree = 70 degree

Answer 2

Answer:

The sum of all three angles should be 180°

let the angle be -ABC

angle a+b-180°=c

so 80°+30°=110°

now subtract 110° from 180°

=70°

Ans=70°

The third angle or angle c measures 70°
