Question
In the figure above, what is the value of x ?
- 45
- 90
- 100
- 105
The correct answer is: 105
HINT – Sum of all the angles of a quadrilateral is 360°
SOLUTION – We know that the sum of all the angles of a quadrilateral is 360°
45° + x + x + x = 360°
45 + 3x = 360
3x = 360 – 45 = 315
x = 
= 105
x = 105°
Hence, option D is correct
