CDEF is a parallelogram. CFG and DHG are straight lines. Find the values of
- ∠r
- ∠v
- ∠t
- ∠s
(a)
∠r
= 180° - 50° - 56°
= 74° (Interior angles)
(b)
∠HCD = ∠HDC = 50° (Isosceles triangle)
∠v
= 180° - 56° - 50° - 50°
= 24° (Interior angles)
(c)
∠t
= 180° - 50° - 50°
= 80° (Isosceles triangle)
(d)
∠s = 56° (Alternate angles)
Answer(s): (a) 74°; (b) 24°; (c) 80°; (d) 56°
