In the diagram above find the value of x - JAMB Mathematics 2006 Question
A
55o
B
50o
C
45o
D
40o
correct option: c
y = 55 (alternate angles)
x = x (same reason)
260 + y + x = 360 (∠s at a point)
260 + 55 + x = 360
315 + x = 360
x = 360 - 315
x = 45o
x = x (same reason)
260 + y + x = 360 (∠s at a point)
260 + 55 + x = 360
315 + x = 360
x = 360 - 315
x = 45o
