Liula [17]2 years ago
3 0

Step-by-step explanation:

Let angle b be x

Let angle a be 4x

Let angle c be 5x

Then,

      4x+x+5x=180(sum of angle of a triangle is 180)

   or,10x=180

   or,x=180/10

      x=18

angle a=4x=4*18=72

angle b=18

angle c=5x=5*18=90

a molecule is measured and the width is 3x10-6 cm. how long will a string of 225 similar molecule be? give your answer in scient
mixer [17]

The length of the molecule is 6.75*10^-^4cm in scientific notation.

Data;

  • Width of molecule = 3*10^-6 cm
  • Number of molecules = 225

<h3>Length of the molecule</h3>

This can be calculated as the total length of the 225 molecules added together. To do this, we simply multiply both the numbers of the molecules by the width of the molecule.

This becomes;

3*10^-^6*225 = 0.000675cm = 6.75*10^-^4cm

The length of the molecule is 6.75*10^-^4cm in scientific notation.
