Answer: The answer is: " x = 11 . "

_____________________________

Step-by-step explanation:

The 2 (two) angles shown form a "right angle" (i.e. "90° angle") ;

that is, the 2 (two) angles are "complementary" (i.e. their measures add up to: " 90° " ,

_____________________

So, add up the 2 (two) given angles, set the sum equal to 90 ; and solve for "x" ; as follows:

_____________________

Note: One of the given angles measures: "5x" ;

The other given angle measures: "35" ;

_____________________

5x + 35 = 90 ;

____________________

Subtract "35" from Each side of the equation:

____________________

5x + 35 - 35 = 90 - 35 ;

to get:

5x = 55 ;

Now, divide Each Side of the equation by: "5" ;

to isolate "x" on one side of the equation;

and to solve for "x" ;

______________________

5x / 5 = 55 / 5 ;

______________________

to get : " x = 11 " .

Hope this answer—and explanation—are helpful to you!

Best wishes!
