Question

Write an equation that can be used to find the value of x in the figure,

Answer 1

Since the two angles form a 90° angle, we can write the following equation:

`12x+30=90`

And solve for x:

`\begin{gathered} 12x+30-30=90-30 \\ 12x=60 \\ (12x)/(12)=(60)/(12) \\ x=5 \end{gathered}`

Answer:

The equation is 12x + 30 = 90

And x = 5
