The angles in a triangle sum up to how many degrees? You should know this from your Trig Textbook.

 

A triangle has 180 degrees.

 

Add up all the angles of the triangle:

 

62  +  43  +  (7x - 16)=180

 

(7x  -16) = 180 - 62 - 43 = 75

 

(7x  -  16) = 75

 

7x = 75 + 16 = 91

 

x = 92 / 7 = 13

 

x = 13 degrees.
