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:

$\begin{gathered} 12x+30-30=90-30 \\ 12x=60 \\ \frac{12x}{12}=\frac{60}{12} \\ x=5 \end{gathered}$

Answer:

The equation is 12x + 30 = 90

And x = 5
