Answer:
7
Step-by-step explanation:
When the mean of two numbers is the same as one of the numbers, then the other number also has that same value. This is true for any kind of mean:
arithmetic, geometric, harmonic.
The other number would be 7.
__
The geometric mean (m) of a and b is ...
m = √(ab)
We have ...
7 = √(7b)
49 = 7b . . . . . square both sides
7 = b . . . . . . . .divide by 7
a = b = m = 7 in this case.
Answer:
Segment Addition Postulate
Step-by-step explanation:
In geometry, the Segment Addition Postulate states that given 2 points A and C(in this case S and O), a third point B(in this case R) lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
Meaning for R to lie on the line SO;
SR + RO must be equal to SO
Answer:
m∠EAE ' = m∠FAF '
Step-by-step explanation:
Rotation is a type of transformation referred to a in which the shape of the original object is preserved and the angle of rotation is constant for all the parts of the body.
Thus, when ΔDEF rotates 90° clockwise about point A to create ΔD 'E 'F.
