Which set of numbers can represent the side lengths, in inches, of an acute triangle? 4, 5, 75, 7, 86, 7, 107, 9, 12

5, 7, 8

Step-by-step explanation:

we know that

If the triangle is an acute triangle

then

applying the Pythagoras Theorem

Verify each case

Remember that the greater side is c

case a) 4, 5, 7

substitute

-----> is not true

therefore

Is not an acute triangle

case b) 5, 7, 8

substitute

-----> is true

therefore

Is an acute triangle

case c) 6, 7, 10

substitute

-----> is not true

therefore

Is not an acute triangle

case d) 7, 9, 12

substitute

-----> is not true

therefore

Is not an acute triangle

answer: i'm not sure

step-by-step explanation:

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
