Answer:

<1 = 50

<2 = 40

<3 = 90

<4 = 90

<5 = 40

<6 = 50

<7 = 130

Step-by-step explanation:

<5 + <6 = 90

40 + <6 = 90

<6 = 50

<5 = <2 because of vertical angles

<2 = 40

<6 = <1 because of vertical angles

<1 = 50

<7 = <4 + <5

<7 = 90 + 40

<7 = 130

Answer:

Solution given:

<4=90°[vertically opposite angle]

<2=<5=40°[vertically opposite angle]

<3=90°[right angle]

again

<1+<2=90°[right angle]

<1=90°-40°=50°

<1=50°

again

<5=40°[given]

<6=<1=50°[vertically opposite angle]

<6=50°

again

<7=<4+<5=90°+40°=130°
