Right triangles must follow the pythagorean theorem, so a^2+b^2=c^2.
Let's find a^2 and b^2 by squaring the first 2 side lengths.
(x^2-1)^2= x^4-2x^2+1
(2x)^2= 4x^2
Then add the two to find c^2
x^4+ 2x^2 +1= c^2
Root both sides
x^2+1=c
Since the side lengths can be plugged into the pythagorean theorem, the side lengths must represent a right triangle.
Hope this helps!
The race was 2.5 miles because an hour divided by 2 is 30 minutes. Therefore you have to do the same thing to the 5 and 2.5 multiplied by 2 is 5.
Answer:
3.14
That is the value of pi to the second decimal point
(-8/3,0) ; (3/5,0) ; (-1,0)
Answer:
Step-by-step explanation:
4/3pi r3=900
pi r3= 675
r3=675*7/22
r3=214
r is about 6 so d=2r=12
