A circle has a circumference of 45 cm. What is the BEST estimate of the circle’s diameter? A) 3 cm B) 7.5 cm C) 15 cm D) 18.5 cm

c. 15 cm

Step-by-step explanation:

c has the BEST estimate!

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
