Answer 1

Answer:

4. 119°,119°

Step-by-step explanation:

because sum of all angles of triangle = 180°

here it is shown that the triangle angles are as follows:

/_1 +/_2+58° =180°

/_1+/_2 =180°-58°

/_1+/_2=122°

and here ot is written that angle 1 and 2 are equal; /_1=61°

/_2=61°

and /_1+/_3=180°(linear pair)

61°+/_3=180°

/_3= 180°-61°

/_3=119°

same process for /_4 also,thenyou will get /_3 and /_4 = 119°,119°
