Find the value of x. The answer choices are. 47, 40, 61, 54. This is not a graded quiz.

Answer 1

The value of x is 54 degrees.

Step-by-step explanation:

The two angles are in a right triangle.

The angles in a right triangle add up to 90. So:

`43\degree+(x-7)\degree=90\degree`

Next, solve for x.

`\begin{gathered} 43-7+x=90 \\ 36+x=90 \\ x=90-36 \\ x=54\degree \end{gathered}`

The value of x is 54 degrees.
