Answer 2

Answer:

the answer is 75 degrees

Step-by-step explanation:

let angle A, B and C be the angles of triangle

and C be the third angle...

since, sum of all angles of triangle is 180 °

therefore,

angle A + angle B + angle C = 180

60°+45°+ angle C = 180°

105° + angle C = 180°

angle C = 180-105

angle C = 75°......ans

hope it helps
