Answer:
1 is 75, 2 is 105, 3 is 30
Step-by-step explanation:
70+35=105
all angles add to 180 in triangles, just need to find the last corner to make 180
180-105= 75 angle1
angle 1 + angle 2 = 180; 75 +angle 2 = 180
angle 2 = 105
use angle 2 and other angle given to find the third number to add to 180
105+45= 150
150 + angle 3 = 180
angle 3 is 30
