Question

solve the problem???? ​

Answer 1

Answer:

119

Step-by-step explanation:

180-(angle1+angle2+58°)

= 180-(2 angle2+58°)

= 180-2angle2-58°

2angle2 = 122

angle 2 = 61

and angle3 = 180-61

= 119

Answer 2

Answer:

angle 3 =119°

Step-by-step explanation:

Let angle 1 and angle 2= x

<1+<2+58°=180°

x+x+58°=180°

2x=180°-58°

2x=122°

x=122°/2

x=61°

<1+<3=180°

61°+<3=180

<3=180°-61°

<3=119°
