Answer 3

These lines are parallel, so 3x - 10 = 70 degrees according to the ALTERNATE ANGLE THEOREM.

Solving for x->
\[3x = 80\]
\[x = {80 \over 3}\]
\[x = 26 {2 \over 3}\]

Answer 4

HMM buut thats not one of the chocies @ParthKohli

Answer 5

Oops, wait

Answer 6

Got it! Yes!

Answer 7

Angle FCD = 110 degrees as they are supplementary angles(add up to 180)
3x - 10 = 110 as THEY ARE CORRESPONDING ANGLES
\[3x = 120\]
\[x = 40\]
