4+5=9
That is all I can see
A is correct
All the other ones are false and if you plug in 3 in the equation, 3(3+9) = 15
Angles along a straight line equal 180. This means that the unmarked angle of the triangle is equal to (180-153)=27.
Angles in a triangle add to 180. This means:
(x-4)+(2x+10)+27=180
3x+33=180
3x=147
x=49
