Hi there. Actually, the image that you have provided us with is a little bit blurry so, if you can make the image a little bit clearer, then I can help you with this question.
Thanks.
The numerical factor<span> of a </span>multiplication expression like 3x<span> is calied a coefficient</span>
Angle c= 60°
This is because 105+25+x=180°
Hope this helps and good luck!! :)
