Answer 1

Answer:

m∠1= 41°

m∠2= 85°

m∠3= 95°

m∠4= 85°

m∠5= 36°

m∠6= 49°

m∠7= 106°

Step-by-step explanation:

To find m∠2

95+m∠2= 180

-95             - 95

m∠2= 85

To find m∠4

Since they are vertical angles, m∠2=m∠4, that means that they are both 85°

To find m∠1

There is four angles in this shape, so the sum is 360 degrees.

90+144+85+m∠1= 360

319+m∠1= 360

-319            -319

m∠1= 41°

To find m∠5

144+m∠5= 180

-144             -144

m∠5= 36°

To find m∠6

m∠5+m∠3+m∠6= 180

36+95+m∠6= 180

131+m∠6= 180

-131             -131

m∠= 49°

To find m∠7

You need to find the sum of the other unidentified angle.

m∠6+m∠=180

49+m∠= 180

-49            -49

m∠= 131

Now you need to find the sum of all the angles in the quadrilateral to get the measure for angle 7.

131+38+85+m∠7= 360

254+m∠7= 360

-254            -254

m∠= 106°
