Question

Can someone help me pls answer chocices a.80 b.180 c.100 d.90

Answer 1

Answer:

<1= 100°

Step-by-step explanation:

<1=<5 Corresponding angles are equal

To find <5

180-80=100

Therefore <1=100

Answer 2

Answer:

c. 100 degrees

Step-by-step explanation:

∠1 and ∠8 have the same angles. ∠7+∠8=180 degrees bc it's a straight line.

therefore we can write this

∠1=∠8

∠8+∠7=180

it gives us the angle to ∠7 so we can now put ∠8 for x and solve

80+x=180

subtract 80 by both sides to isolate x

x=100

hope this helped!!
