Though these segments aren't marked congruent in the diagram, the two lines inside the circle making up the bases of the triangles are congruent as all radii are congruent. So the triangles are congruent by SAS.
A square is basically two triangles put together and since a square has four right angles you can use the Pythagorean Theorem to do this.
A squared +b squared <24
5 squared x 5 squared = 25
Sooooooo...... ;)
Get it?
So c-9 is less than or equal to 20 so c is less than or equal to 29. So the correct answer is c. Hope this helps :)
Answer:
22 inch is the diameter because d =2r
Initial number of Bacteria = Ao = 100
Number of Bacteria which make the person ill = A = 45,000,000
Growth rate = r = 150% = 1.50
The equation model for this situation is:

Using the values in above equation, we can write:
This means, the person will fall sick after about 14 hours.
