A) the only mistake is changing the mixed number to an improper fraction .
The answer is 5.83
Use the Pythagorean Theorem to calculate the 3rd side length.
a^2+b^2=c^2
3^2+5^2=c^2
Answer:
2.75
Step-by-step explanation:
to get the mean all you have to is add all the numbers up then divide by how numbers there are. so 3e is what u get when u add them up then divide by 12 and u get 2.75
You can apply the Pythagorean theorem:
a^2 + b^2 = c^2
c is the longest side of the triangle
2.2^2 + 4.2^2 = 6.7^2
4.84 + 17.64 = 44.89
22.48 =/= 44.89
That is not a right triangle
Answer:
if 5x + 2 = 7x - 7 then the answer is x = 9/2.
