The measure of an angle is 2 times the measure of its complement. Tina writes an equation and finds the correct measure of each angle.

Which shows the equation Tina could have written and the angle measures she could have found?

•  $2x\ +x=90:\ 60\degree and\ 30\degree$  

•  $\left(x+3\right)+3=90:\ 71\degree\ and\ 19\degree$  

•  $\left(x+3\right)+3=180:\ 86\degree\ and\ 94\degree$  

•  $3x\ +x=180:\ 135\degree and\ 45\degree$
