Question

If m∠1 ≅ 115°, find m∠8. answers : 205° 115° 65° 25°

Answer 1

The answer would be 65°

It would be 65° because my the corresponding angles postulate angle 1 and angle 5 are congruent. Angle 5 and angle 8 are supplementary.

If Angle 5 + Angle 8 = 180
Then plug in values

115 + angle 8 = 180

angle 8 = 65

Answer 2

Answer:

65°

Step-by-step explanation:

∠1=115°

∠2=65°

∠3=65°

∠4=115°

∠5=115°

∠6=65°

∠7=115°

∠8=65°

We get this because Line m and l are parallel. Also ∠1+∠2=180° so if ∠1 is 115°, then ∠2 is 180°-115° or 65°.
