Answer:
10√5
Step-by-step explanation:
The geometric mean of two numbers is the square root of their product.
m = √(20×25) = √500 = √100 × √5
m = 10√5
The geometric mean of 20 and 25 is 10√5.
Answer:
Answer A
Step-by-step explanation:
Approach 1
B, C, and D are wrong because angles 1 and 2 are congruent.
Therefore your answer of both being 60°
Approach 2
Let x = angle 1.
360/x = 6
x = 60°.
Therefore Angle 1 is 60°
An interior angle of a hexagon is 120°
Let y = angle 2.
y is half of 120°
So 120/y = 2
y = 60°
