Explanation:

Geometric mean = 7.3

Answer 2

#1

This is the isosceles right triangle as one of the angles is 45°.

The second leg is same as the first and the hypotenuse is √2 times the leg.

• x = 5√2
• y = 5

#2

This is the 30°x60°x90° triangle and the ratio of sides is:

• 1 : √3 : 2

Since the hypotenuse is 16, the other sides are:

• y = 16/2 = 8
• x = 8√3

#3

Geometric mean of two numbers is the square root of their product.

• √9*6 = √54 = 7.3 (rounded)

Correct choice is C
