Question

Can someone help me?

Answer 1

In the figure you can say ∠1 + ∠4 = 180° because both together make a line so you can say : 63° + ∠4 = 180° ⇒ ∠4 = 180° - 63 ° = 117 ° so the answer is :
∠4 = 117° :)))
i hope this is helpful 
have a nice day 

Answer 2

Since j is a straight line, angle 1+angle 4=180
angle1=63
find angle 4
angle1+angle4=180
63+angle4=180
subtract 63 from both sidess
angle4=117
the answer is 117 degrees
