Answer:
x=65*
Step-by-step explanation:
theres a small rectangle near x and it means that the angle is 90*
and the upper angle is 180
180+90+25+x=360*
x=65*
You can solve this with next proportion =>
3 : 5 = 4 : x => 3x= 5*4 => 3x = 20 => x=20/3 = 6 (2/3)
The correct answer is x= 6 (2/3)
Good luck!!!
