PLS HELP ME NOW ITS PYTHAGOREAN THEOREM
rusak2 [61]

Answer:

a =2.2

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2

where a and b are the legs and c is the hypotenuse

a^2+2^2 = 3^2

a^2 +4 = 9

a^2 = 9-4

a^2 = 5

Taking the square root of each side

sqrt(a^2) = sqrt(5)

a = sqrt(5)

a=2.236067977

To the nearest tenth

a =2.2

Dana walks 3/4 miles in 1/4 hours. What is dana's walking rate in miles per hour?
Harman [31]

Dana’s waking rate in miles per hour is 3 mph.

I did 3/4 x 4 = 3 because she walked 1/4 a mile and I needed to figure out the miles per one whole hour.

I hope this made sense and helped you.
