The answer is going to be 1/9
Answer:
A.) 13
Step-by-step explanation:
Since DB =36, and AC is the same line, then AC = 36. The new equation is 36 = 3x - 3. Do inverse operation. Add 3 to both sides of the equation: 36+3=39 & -3+3=0. New equation is 39=3x. Finally divide. 39/3= 13.
You know that D is 35° cause of the angle next to F. and <E=180-(120+35) so E is 25°
2x + 7y + 2 = 0
2(-1) + 7(-3) + 2 = 0
-2 - 21 + 2 = 0
-21 = 0
