Answer:
m∠5 = 77
Step-by-step explanation:
∠3 & ∠5 are the co interior angles in the same side of the transversal
∠3 + ∠5 = 180 {sum of co interior angles is 180}
3x + 4 + 2x +11 = 180 Â {Add like terms}
5x + 15 = 180
Subtract 15 from both sides
5x + 15 - 15 = 180 -15
5x = 165
Divide both side by 5
5x/5 = 165/5
x = 33°
m∠5 = 2x + 11 = 2*33 + 11
    = 66 + 11
    = 77
