Question

Help please this is timed ! It is an assignment that I have to get done thank u

Answer 1

This is a right-angled triangle and to solve for the unknown side we will use the Pythagoras theorem.

Given parameters:

Opposite side= 15

Adjacent side = 12

Hypotenuse side = x

Pythagoras theorem:

`\text{hypotenuse}^2=opposite^2+adjacent^2`

Substituting the given parameters into the equation above, we will have:

`\begin{gathered} x^2=15^2+12^2 \\ x^2=225+144 \\ x^2=369 \\ \sqrt[]{x^2}=\sqrt[]{369} \\ x=19.2094 \\ x=19.21(\text{to the nearest hundredth)} \end{gathered}`

Final answer: x = 19.21
