The third angle will measure 115° so option (A) will be correct.
What is a triangle?
The three-sided shape known as a triangle is sometimes used to allude to it. Every triangle has three sides and three angles, some of which might be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
Sum of all three internal angles of the triangle = 180°
Sum of two angles + third angle = 180°
Given that,
Two angles of a triangle add up to 65° so
65° + third angle = 180°
Third angle = 180 - 65°
Third angle = 112°
Hence the third angle will be 112° measure.
