PLEASE MARK AS BRAINLIEST I NEED THEM TO MOVE UP A RANK PLZ

Step-by-step explanation:

1.  57+52=109 angle in a triangle is 180 degrees so 180-109=71

you answer is 71

2. 58+90=148 take away 180 =32

     your answer is 32

3. 36+26=62  180-62=18  

   your answer is 19

4.  38+25=63  180-63=17

     you answer is 17

Answer 2

Answer:

1.71°

2. 32°

3. 118°

4. 117°

Step-by-step explanation:

Here we use angle sum property of a triangle the sum of all the angles of a triangle is 180° always and for solving these questions this method is used

1. 57° + 52° + x = 180°

109°+ x =180°

x= 180° - 109°

x = 71°

And similarly we done in all the other questions
