Answer:
(b).∠ABC is bisected by ray BD.
(c) BC = One-half of AC
(e) 2 ∠DBC = ∠ABC
Step-by-step explanation:
Here ray AC and ray BD is perpendicular to each other.
Thus, Option (a) is not true as ∠DBC is not bisected by any ray.
Option (b) is correct.
Option (c) is also correct as B is the mid-point of AC.
Option (d) is also incorrect as length of line segment DB and line segment BC can be different.
Option (e) is also correct.
Answer:
angle ABC is bisected by BD
BC= halfAC
2mangleDBC=mangleABC

The number 7/10 is a rational number.
A rational number is any number that can be expressed as the ratio of two integers, where the denominator is not zero.
In the case of 7/10, both the numerator (7) and the denominator (10) are integers.
Since 7/10 can be written as the fraction of two integers, it falls under the category of rational numbers.
Rational numbers can be expressed as fractions or terminating or repeating decimals.
In this case, 7/10 can be written as the fraction 7/10 or as the decimal 0.7, which is a terminating decimal.

Rational. Hope that helps!
and the length is
Answer:
width=6cm, lenth is 7cm
Step-by-step explanation:
Let width of rectangle be x cm
Twice width=2x cm
length=2x-5 cm
Area of the rectangle= L× W =42cm²
(2x-5) × x =42
x(2x-5)=42
2x²-5x-42=0
solving the quadratic equation
x=6cm
width=6cm
length= (2×6)- 5 =7cm
