JKLM is a parallelogram. JMN and KPN are straight lines. Find the values of
- ∠t
- ∠x
- ∠w
- ∠v
(a)
∠t
= 180° - 53° - 56°
= 71° (Interior angles)
(b)
∠PJK = ∠PKJ = 53° (Isosceles triangle)
∠x
= 180° - 56° - 53° - 53°
= 18° (Interior angles)
(c)
∠w
= 180° - 53° - 53°
= 74° (Isosceles triangle)
(d)
∠v = 56° (Alternate angles)
Answer(s): (a) 71°; (b) 18°; (c) 74°; (d) 56°
