Let be a, b, c be the lengths of sides of a triangle; a=4.8, b=0.23, c is a whole number. Find c.

makvit [3.9K]

It's not clear if this is a right triangle or not. I'm going to assume its any kind of triangle. The third side c is restricted such that...

a - b < c < a + b
4.8 - 0.23 < c < 4.8 + 0.23
4.57 < c < 5.03

If c was allowed to be any real number, then we'd have infinitely many solutions for c. However, we're told that c is a whole number. The only whole number between 4.57 and 5.03 is 5

So c = 5 is the only integer solution

Final Answer: 5

What is the area of quadrilateral QRST if QS=18 and RT=24. Show work.

lana [24]

Answer:

$\text{Area of quadrilateral QRST}=216$

Step-by-step explanation:

Please find the attached image for the quadrilateral QRST.

We have been given that $QS=18 \text{ and } RT=24$ . We are asked to find the area of quadrilateral QRST.

Upon looking at the image of quadrilateral QRST, we can see that quadrilateral QRST is a kite as it has one pair of diagonally opposite equal angles (98 degrees).

We know that area of kite is equal to half the product of its diagonal.

We can see from our image that QS and RT are diagonal of kite, so the area of quadrilateral QRST would be:

$\text{Area of quadrilateral QRST}=\frac{QS\cdot RT}{2}$

$\text{Area of quadrilateral QRST}=\frac{18\cdot 24}{2}$

$\text{Area of quadrilateral QRST}=\frac{432}{2}$

$\text{Area of quadrilateral QRST}=216$

Therefore, the area of quadrilateral QRST is 216 square units.
