dis is choose da correct please help

Answer 1

Answer:

b)x=115 degrees

Step-by-step explanation:

three angles of a complete angle is given to us;

x,x+10 and 120

we know the sum of all the angles of a complete angle is 360 degrees,

therefore,

                 x+(x+10)+120=360

=>2x+130=360

=>2x=360-130

=>x=230/2

x=115 degrees
