Answer 1

this question is wrong bro because sum of angles of triangle is 180° and in question given that two angles sum is 650° which is greater than 180°

although here is the solution

<A+<B=650°

<B+<C=1400°

by adding both equations

<A+<B+<B+<C=2050°

180°+<C=2050°

<C=1870°

Answer 2

Answer:

angle A=40° ; angle B=25° and angle C=115°
