Find the value of x. ROUND TO THE NEAREST TENTH

Given:

Hypotenuse = 2.1 ft

Height = 1.4 ft

To find:

The value of x.

Solution:

There is a right triangle in circle.

Let b be the base of the triangle.

Using Pythagoras theorem:

Subtract 1.96 on both sides.

Taking square root on both sides.

b = 1.56

The line from the center of the circle bisect the chord.

So x = 2b

x = 2 × 1.56

x = 3.12

x = 3.1 (nearest tenth)

The value of x is 3.1 ft.

the discriminant is 64 + 4*1*12 = 112

this is prime.
