Answer:
37.5%
Step-by-step explanation:
25 + (1 - m) * 40
25 = 40*1 - 40*m
25 =40 - 40m
25 = 40 + (-40m)
-40 = -40
-15 = 40m
/40 = /40
=0.375 = m
37.5% = m

If this is in terms of angles, 4x+6 must be equal to 90 since it is half of the angle produced by a line (180°) So solving for 4x+6=90, x=21
(x+4)+(x+4)+(x+7)+(x+7)
