In the diagram Pq TS TU reflex angle QPS 245o a... - WAEC Mathematics 2011 Question
In the diagram /Pq//TS//TU, reflex angle QPS = 245o angle PST = 115o, , STU = 65o and < RPS = x. Find the value of x
A
80o
B
70o
C
60o
D
50o
correct option: d
< QPR = < STU = 65o (Corresponding angles)
245 + < QPR = x = 360o (< s at a point)
i.e. 245 + 65 + x = 360
x = 360 - (245 + 65)
x = 360 - 310
x = 50o
245 + < QPR = x = 360o (< s at a point)
i.e. 245 + 65 + x = 360
x = 360 - (245 + 65)
x = 360 - 310
x = 50o
