Hope it helps

Answer 2

Answer:

given below  is the solution to the 7th question.

Step-by-step explanation:

Given=AB//CD//EF

<ABC=70°

<CEF=130°

TO FIND= ANGLE X

PROOF=EF//CD

THEREFORE,<CEF+<ECD=180(angles on same side of transversal are supplementary)

130°+<ECD=180°

<ECD=180-130=50°

ALSO, AB//CD

<ABC=<BCD

SO,>BCD=70 °(interior alternate angles when AB//CD)

but <BCD=X+<ECD

70=X+50

X=70°-50°=20°

THEREFORE, x=20°

hope it helps you.

good night
