2L+2W=157.5
L=W-30
2(W-30)+2W=157.5
2W-60+2W=157.5
+60 +60
4w=217.5
W=54.4(.37 rounded to nearest tenth)
L=24.4
Angle DAC = 180-25 = 155 degrees
Angle ABC = 180 - 146 = 34 degrees
Angle ADC = 180 - 149 = 31 degrees
ABCD is a quadrilateral and angles in quadrilateral add up to 360 degrees
Angle BCD = 360 - (155 + 34 + 31)
= 360 - 220
= 140 degrees
