What's the equation to find the midpoint of a right triangle?

Viktor [21]

The answer is 20. You have to use the Pythagorean theorem (A^2+B^2=C^2) to find the length of the hypotenuse.

32^2+24^2=C^2
1024+576=C^2
1600=C^2
Take the square root of both sides
40=C
Since the midpoint is the middle, you divide the length of the hypotenuse by 2 and get the answer (20)

Y varies directly as xy equals 5 when X is 8 how do you find y when X is 9

FrozenT [24]

Given, y varies directly as x

So,

$y=c\cdot x$

Where c is a constant

When y equals 5 when x is 8

So,

$\begin{gathered} 5=c\cdot8 \\ c=\frac{5}{8} \\ \end{gathered}$

So, the relation between y and x

$y=\frac{5}{8}x$

now , when x = 9

Substitute with x to find y

$y=\frac{5}{8}\cdot9=\frac{45}{8}$

So, the answer is option 2. y = 45/8

Any help would be appreciated. Thank you!

Answer:

Area $=62.5\sqrt{6}$ square units

$AB=5\sqrt{15}$ units

$BC=5\sqrt{10}$ units

Step-by-step explanation:

In a right triangle the altitude drawn to the hypotenuse is the geometric mean of the segments at which this altitude divides the hypotenuse.

So,

$BD^2=15\cdot 10\\ \\BD^2=150\\ \\BD=\sqrt{150}=5\sqrt{6}\ units$

a. The area of the triangle ABC is

$A_{ABC}=\dfrac{1}{2}\cdot BD\cdot AC=\dfrac{1}{2}\cdot 5\sqrt{6}\cdot (15+10)=\dfrac{125\sqrt{6}}{2}=62.5\sqrt{6}\ un^2.$

b. The legs of the right triangle are geometric means of the segment adjacent to this leg and the hypotenuse, so

$AB^2=AD\cdot AC=15\cdot 25\Rightarrow AB=5\sqrt{15}\ units\\ \\BC^2=CD\cdot AC=10\cdot 25\Rightarrow BC=5\sqrt{10}\ units$

Three less than twice a number is 15.

inessss [21]

Answer:

3-2x=15

Step-by-step explanation:

add 3 to both sides makes -2x=18. divide -2 from both side gets the answer x=-9, so the answer is C, -9
