Answer:
number 3 or 6 ^w^
your welcome for the help
Answer: 38.97
10% of 40 is 4
40-4=36
8.25% of 36 is 2.97
36+2.97= 38.97
Heron's formula is named after Hero of Alexendria, a Greek Engineer and Mathematician in 10 - 70 AD. You can use this formula to find the area of a triangle using the 3 side lengths.
Therefore, you do not have to rely on the formula for area that uses base and height. The picture below illustrates the general fro mu la where S represents the semi-perimeter of the triangle ,
Answer:
It would be at a depth of 42 meters below the surface
Step-by-step explanation:
13(6)=78 -120+78=-42
Answer:
it is a right triangle.
Step-by-step explanation:
you would solve by using pythagorean theorem. Firstly you would find the square roots. Then write the pythagorean theorem out replacing the variables with the corresponding numbers. All you do for this is find the greatest number and that is c. Lastly you would add the square roots of a and b, if this equals 28 then they are equal.
