Answer:
1=153°
2=27°
3=95°
Explanation:
106+47=153 There are 180° in a triangle and you want to 180-153=27 find what left in the smaller one
180-153=27
Now you do 180- 27=153 because In a straight line there is 180°
so one is 153
as I said in a straight line there are 180° so you do
180-153= 27 to find out 2
and because there are 180° in a triangle you add 27 and 58 then take that from 180 to find 3
27+58=85
180-85=95
