Answer:

Solution:

(i) \angle B+\angle C=180\degree∠B+∠C=180° [Supplementary angle theorem}

\therefore100\degree+x=180\degree∴100°+x=180° [Given]

x=180\degree-100\degreex=180°−100°

x=80\degreex=80°

\rm\underline\bold{Answer \purple{\huge{\checkmark}}}

Question 1.

 \sf \: x+100=180 \:  \:  \:  \:  [Adjacent \:  angles]

 \sf \implies x=80

 \sf \implies \: z=x=80°

ㅤㅤㅤㅤㅤㅤ[opposite angles are equal]

 \sf \implies \: y=100°

ㅤㅤㅤ

Question 2.

 \sf \: 50+y=180

 \sf \implies \: y=130°

 \sf \implies \: x=y=130°

 \sf \implies \: z=x=130°

ㅤㅤㅤㅤㅤㅤ(corresponding angles)

ㅤㅤ

Question 3.

 \sf \: x=90°

ㅤㅤㅤㅤㅤㅤ(vertically opposite angles)

 \sf \implies \: x+y+30=180°

 \sf \implies \: y=180−120=60°

 \sf \implies \: z=y=60°

ㅤㅤㅤㅤㅤㅤㅤ(Alternate angles)

Question 4.

 \sf \: z=80,y=80  \:  \:  \:  \:  \:  \: (Opposite \:  \:  angles)

 \sf \implies \: x+y=180°

 \sf \implies \: x=180−80

  \sf \implies \: x=100

ㅤㅤ

Question 5.

 \sf \: y=112°

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ (opposite angles)

 \sf \implies \: x+y+40=180°

ㅤㅤㅤㅤㅤㅤㅤㅤ (Angle sum property)

 \sf \implies \: x=180−152

 \sf \implies \: x=28°

 \sf \implies \: z=x=28°

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ(Alternate angles)

It helps you!!
