In ΔDEF shown below, segment DG is an altitude:
Tju [1.3M]
I found the corresponding image.

The step towards proving the similarity of triangles DEF and GED is:

ANGLE E IS CONGRUENT TO ITSELF.

ΔDEF is a right triangle. Its hypotenuse is EF, its long leg is DF, its short leg is DE.
ΔGED is also a right triangle. Its hypotenuse is DE, its long leg is DG, its short leg is GE.

Only Angle E is in both triangles and its measure remains the same.

A her of 40 horses has 9 white and some black horses. What is the ratio of white to black horses?​
solmaris [256]

Answer:

The number of white horse to white horse is 9 : 31

Step-by-step explanation:

Given as :

The Total number of horses = 40

The number of white horses = 9

Let the number of black horses = x

So, x + 9 = 40

Or x = 40 - 9 = 31

∴ The number of black horses = 31

Now,  The ratio of while to black horses = number of white horse : number of black horse

Or, number of white horse : number of black horse = 9 : 31

Hence The number of white horse to white horse is 9 : 31   Answer

The circumference of the hub cap of a tire is 82.14 centimeters. Find the area of this hub cap. Use 3.14 for pi
earnstyle [38]

Answer:

Circumference = 2 * radius * 3.14

82.14 = 2*3.14 r

r= 82.14/6.28=13.079 cm.

So the area = 3.14 r^2

3.14*13.079^2

537.129 cm ^2

Hope this helps :)
