If the diagonals of a quadrilateral bisect the angles, is the quadrilateral always a parallelogram? Explain your answer.
Liula [17]
Yes. If the diagonals bisect the angles, the quadrilateral is always a parallelogram, specifically, a rhombus.


Consider quadrilateral ABCD. If diagonal AC bisects angles A and C, then ΔACB is congruent to ΔACD (ASA). Hence AB=AD and BC=CD (CPCTC).

Likewise, if diagonal BD bisects angles B and D, triangles BDA and BDC are congruent, thus AB=BC and AD=CD. (CPCTC again). Now, we have AB=BC=CD=AD, so the figure is a rhombus, hence a parallelogram.

Hi i need help with 15a(ii)
Art [367]

Answer:

x = 5/2

Step-by-step explanation:

log4(x^2+5x)-log8(x^3)=1/log3(4)

log(x^2 + 5 x) / log(4) - log(x^3) / log(8) = log(3) / log(4)

log(x (x+5))/log(4) - log(x^3) / log(8) = log(3) / log(4)

(3 log(x (x+5)) - 2 log(x^3)) / log(64) = log(3) / log(4)

3 log(x (x+5)) - 2 log(x^3) = 3 log(3)

log((3 x)/(x+5))=0

x=5/2

Your cat weighs 12 pounds. How much does she weigh in ounces?
Elanso [62]

Answer:

192 ounces does she weigh in ounces.

Step-by-step explanation:

Unit rate defined as the rates expressed as a quantity of 1, such as 3 feet per second or 8 miles per hour, they are called unit rates.

As per the given statement: Your cat weighs 12 pounds.

We have to find the cat weighs in ounces.

Use conversion:

1 pound = 16 ounces.

⇒\text{Unit rate per pound} = 16 \text{ounces}

then by definition of unit rate;

\text{Cat weighs in ounces} = \text{Unit rate per pound} \times 12

Substitute the given values we have;

\text{Cat weighs in ounces} = 16 \times 12 = 192 ounces

therefore, your cat weighs in ounces is, 192 ounces
