Find the length of the hypotenuse of a right triangle with legs of 9 cm and 12 cm.
a) 8 cm
b) 21 cm
c) 15 cm
d) 225 cm
Use the pythagorean theorem:
c^2 = a^2 + b^2
where
c = hypotenuse
a = one leg
b = the other leg
In the problem,
a = 9
b = 12
Now solve for c using the equation above.
i need help but on one helps me with my math ugh
its C
c never mind its c
To find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the two legs.
In this case, the legs of the right triangle are 9 cm and 12 cm. Let's call the hypotenuse "c".
The Pythagorean theorem can be written as:
c^2 = 9^2 + 12^2
Simplifying, we have:
c^2 = 81 + 144
c^2 = 225
To find the value of "c", we need to take the square root of both sides:
c = sqrt(225)
c = 15
Therefore, the length of the hypotenuse of the right triangle is 15 cm.
So, the correct answer is c) 15 cm.
