Find the heigh of the kite

The height of the kite rounded to the nearest tenth is “6.6ft.” To find this answer you can use the basic formula to find the hypotenuse which is a^2 + b^2 = c^2. Where a and b are the two sides and c is the hypotenuse. We have one side and the hypotenuse so we can plug the numbers into the equation like so 10^2 + b^2 = 12^2. Solve for b 100 + b^2 = 144 subtract 100 to both sides to get b^2 = 44. Now all you have to do is find the square root of 44 which turns out to be 6.63324958071 but we are just rounding to the nearest tenth. So your answer results to 6.6ft

Have a nice day!

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
