If three angles of a quadrilateral are each equal to 75°, the fourth
angle is
(a) 150° (b) 135° (c) 45° (d) 75°
X ∪ Y means divide X by Y
X ↑ Y means multiple X by Y
X # Y means subtract Y from X
X ∩ Y means add Y to X
Ex 9. One-fifth of one-tenth of two-third of a number X is given by
(A) X ↑ (1∪ 5) ↑ (1∪10) ↑ (2 ∪ 3) (B) (X 1 ↑ 5)(1 ↑ 10)(2 ↑ 3)
(C) (X 1 ↑ 5)(2 ↑ 10)(2 ↑ 3) (D) can’t be determind
Application on the problem solution strategy
Construct a rhombus with side 4.5cm and diagonal 6cm.
If A + D > C + E, C + D = 2B and B + E > C + D, it necessarily follows that
(A) A + B > 2d (B) B + D > C + E (C) A + D > B + E (D) A + D > B + C
Application on the problem strategy
RICE is a rhombus. Find x, y, z.
Justify your findings. Hence, find the
perimeter of the rhombus.
