How do you find geometric mean of a triangle

2 answers:

Norma-Jean [14]4 years ago

Answer:

Step-by-step explanation:

The geometric mean is the positive square root of the product of two numbers. If we in the following triangle draw the altitude from the vertex of the right angle then the two triangles that are formed are similar to the triangle we had from the beginning. The two triangles formed are also similar to each other.

What is the value of c, d, a, and b?

amid [387]

Answer:

a=101

b=67

c=84

d=80

Step-by-step explanation:

The measure of an intercepted arc will always be twice the measure of the inscribed angle

to find A:

2(100)=a+99

200=a+99

a=101 degrees

d=80 degrees because 100*2=200, 360-200=160, and 160/2=80

You can find c by subtracting 100, 96, and 80 from 360 and you get c=84 degrees

Find the measure of b by using what you found as measure of c and a

2(84)=101+b

168=101+b

b=67

18. Find the center, vertices, and foci of the ellipse with equation x squared divided by 225 plus y squared divided by 625 = 1.

KengaRu [80]

Answer:

Center (0,0)

Vertices (-15,0), (15,0), (0,-25), (0,25)

Foce (0,-20), (0,20)

Step-by-step explanation:

You are given the ellipse equation

$\dfrac{x^2}{225}+\dfrac{y^2}{625}=1$

The canonical equation of ellipse with center at (0,0) is

$\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1$

So,

$a^2=225\Rightarrow a=15\\ \\b^2=625\Rightarrow b=25$

Hence, the center of your ellipse is at (0,0) and the vertices are at points (-15,0), (15,0), (0,-25) and (0,25)

This ellipse is strengthen in y-axis, so

$c=\sqrt{b^2-a^2}=\sqrt{625-225}=\sqrt{400}=20$

and the foci are at points (0,-20) and (0,20).

Can you help me solve this equation?

MakcuM [25]

Answer:

-2

Step-by-step explanation:

25x+30+9+12x=-35
