Answer:

Q1(a). x=112 (corr angles)

Q1(b). x=75 (alt angles)

Q1(c). x=180-150 (adj angles on a str line)

=30

y=150 (corr angles)

Q1(d). x=99 (vert opp angles)

y=99 (corr angles)

z=180-99 (adj angles on a str line)

=81

Q1(e). x=180-74 (adj angles on a str line)

=106

y=106 (corr angles)

Q1(f). x=123 (corr angles)

y=180-110 (int angles)

=70

Q3. 4x+15=5x-10 (vert opp angles)

4x-5x=-10-15

-x=-25

x=25

Q4. x+22+2x-13=180 (int angles)

3x+9=180

3x=180-9

=171

x=171รท3

=57
