Question

Do not understand please help
Thank u

Answer 1

Use the Pythagoras' theorem

-the square of the hypotenuse equals to the sum of the squares on the other two side:

a^2 = b^2 + x^2

-given the hypotenuse and another side and asked to find the missing side:

Therefore you play with the equation to make the missing side the subject of formula as I did above.

Answer 2

43.4

Explanation:

You will need to use the phythagoream therom, which is a² + b² = c². Plug the values in for the variables to get 7² + b² = 44², (c would equal the hypothenuse because the hypothenuse is the longest side of the triangle.) Square the values to get 49 + b² = 1936. Subtract 49 from both sides to get b² = 1887, then take the square root of both sides to get b = 43.4 (rounded to the nearest tenth.)

I am really sorry if I'm wrong, but have a good day/night! :)
