2.1*10^8 is how many times the value of 4.2*10^2

The answer is 500,000 times the value.

Do the division:-

2.1 * 10^8 / 4.2 * 10^2

= 0.5 * 10^6

= 5 * 10^5

= 500,000

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.
