Question

17. What is the measure, in degrees, of angle x?

Answer 1

Let ,

130° + y = 180° — ( i )

x + 107° + y = 180° — ( ii )

now ( i )

130° + y = 180°

y = 180° - 130°

y = 50°

now substituting value of y in equation ( i )

`x + 107 + y = 180 \\ x + 107 + 50 = 180 \\ x + 157 = 180 \\ x = 180 - 157 \\`

x = 23°
