Question

I need help on 4 please it says find the value of x round each answer to the nearest tenth

Answer 1

The pythagorean theorem is :

`c^2=a^2+b^2`

where c is the hypotenuse

a and b are the legs of the triangle.

From the problem, a = x, b = 19.1 and c = 30.5

Using the formula :

`\begin{gathered} 30.5^2=x^2+19.1^2 \\ 930.25=x^2+364.81 \\ x^2=930.25-364.81 \\ x^2=565.44 \\ x=\sqrt[]{565.44} \\ x=23.779 \end{gathered}`

The answer rounded to the nearest tenth is x = 23.8
