Answer:
1= 41
2= 85
3= 95
4= 85
5= 36
6= 49
7= 106
Step-by-step explanation:
I'm going to go in the order I filled them in.
3: angles that are across from each other are the same. 3 is across from the angle measured 95, so that's what 3 is.
4: We know that a line is 180 degrees. So, subtract 95 from 180:
180 - 95 = 85.
2: same for four, because two angles across from each other are the same.
5: Similar to 2 and 4. A line is 180. So, we subtract 144 from 180:
180 - 144 = 36
7: Use the large triangle on the right (the one with 38, number 7, and number 5). A triangle's angles always add up to be 180. So, subtract 38 and 36(answer to number 5) from 180:
180 - 38 - 36 = 106
6: Use the small triangle in the middle (angles 3, 5 and 6). We know angle 3 is 95 and angle 5 is 36. A triangle's angles are 180, so subtract:
180 - 95 - 36 = 49
1: Use the left triangle (angles 1, 6 and the 90 degree angle). We know angle 6 is 49, so subtract. Remember, a square in the corner is 90 degrees:
180 - 90 - 49 = 41
I hope this helps :)
