Answer: x = 16
Step-by-step explanation:
If RQ is the bisector, that means the angle is cut in half. Therefore angles PRQ and QRS are equal to each other.
4x+6 = 7x-42
subtract 7x from both sides
-3x+6 = -42
subtract 6 from both sides
-3x = -48
divide both sides by -3
x = 16
Answer:
50 cm² and 56 cm²
Step-by-step explanation:
The area (A) is calculated as
A =
× d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )
(2)
A =
× (8 + 2) × (5 + 5)
= 0.5 × 10 × 10
= 5 × 10
= 50 cm²
(3)
A =
× (12 + 2) × (4 + 4)
= 0.5 × 14 × 8
= 7 × 8
= 56 cm²
Trapezoid : A= (a+b/2)h
a and b are the bases of the trapezoid
h is the height
kite: A= pq/2
p is the diagonal
q is the other diagonal
