Use the figure to find the measures of the numbered angles. m∠1=
∘, m∠2=
∘, m∠3=
∘, m∠4=
∘, m∠5=
∘, m∠6=
∘, m∠7=

Step-by-step explanation:

consider 61°=m angle 8

angle 1=angle 8 corresponding angle

angle 1=61°

angle 2+angle 1=180°angles in linear pair

180-61

angle 2=119°

angle 3=angle 8 alternate angle

angle 3=61°

angle 4=angle 2 opposite angles

angle 4=119°

angle 5=angle 4 alternate angles

angle 5=119°

angle 6=angle 8 opposite angles

angle 6=61°

angle 7=angle 5 opposite angles

angle 7=119°

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
