C: SAS

Step by step:
The first side is the side that was already established is the same as the other (ab & bc) The angles from point b are congruent because it’s an isosceles triangle so the mid point of the base is the altitude of the triangle and angle bisector of the angle opposite of it. Since it’s an angle bisector both are equal. The third side is the one that they share (bd). Then using SAS you can prove congruency.
Hope that helps :)

How do you tell if a number is irrational or rational?
Korvikt [17]
A rational number is any number that can be expressed as a fraction
(ex: -5/2, 4 1/7, and 8/13)

An irrational number is any number that cannot be expressed as a fraction; a non-repeating, non-terminating decimal (ex: pi, 0.121231234...)

the main rotor of a helicopter rotates 430 times per minute. find the number of degrees through which a point on the main rotor
n200080 [17]

Answer:

2580 degrees rotated per second

Step-by-step explanation:

since  you have to find the degrees it rotates per second.

you need to divide 430 by 60 to find rotations per second

1)          430/60

             =  7.16666667 rotations per second

-then you have to multiply it by 360 degrees ,because their is 360 degrees in a circle

2)        7.16666667 (360)

            =  2580 degrees rotated per second

2. 1/4 km=1000/4=250 meters

3. 1/5 km=1000/5=200 meters

4. 2/5 km=2000/5=400 meters
