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
The product is C. -20. Good luck!
Answer:
C
Step-by-step explanation:
7+5 makes 12 which is the same as 3+4+5 which is 12
x - 4
4 less than x means that we subtract 4 from x.
