Write the ratio in fractional notation in lowest terms. 28 inches to 42 inches

Answers

28 to 42 means 28/42

We now reduce 28/42 to lowest terms.

28 ÷ 7 = 4

42 ÷ 7 = 6

We now have 4/6.

We now reduce 4/6.

4 ÷ 2 = 2

6 ÷ 2 = 3

Final answer: 2/3

The formula for the length of the hypotenuse in a right triangle is squared a^2+b^2 where a and b are the lengths

Answers

Answer:

the hypotenuse in a right triangle formula is c= sqrt(a^2+b^2)

Step-by-step explanation:

The original Pythagorean's theorem equation is a^2+b^2=c^2 which we can take the square root of to isolate and solve for the equation for just the hypotenuse length. This of course is assuming that a and b are the legs of the triangle. Let me know if this wasn't what you were asking or if you need more clarification and I'll amend my answer
