Question

in the figire shown, t || x and k || w and m<3=20°. Choose the list which includes all of the other angles that measures 20°​

Answer 1

Answer: (d)

Explanation:

Given

`\angle 3=20^(\circ)`

from the figure, we can write

`\angle 1=\angle 3\quad [\text{vertically opposite angles}]`

`\angle 3=\angle 7\quad [\text{corresponding angles}]\\\angle 5=\angle 7\quad [\text{vertically opposite angles}]`

`\angle 1=\angle 16\quad [\text{corresponding angles}]`

Also,

`\angle 16=\angle 14\quad [\text{vertically opposite angles}]`

`\angle 14=\angle 9\quad [\text{corresponding angles}]`

`\angle 9=\angle 11\quad [\text{vertically opposite angles}]`
