Find the missing angles

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 :)
