ABCD is a paralleogram in which angel B=110degree.find the values of Xand Y
Answers
Answer:
y = 40°
X = 30°
Step-by-step explanation:
Since y is an alternative angle of A which is 40° y is also 40°.
ABC form a triangle in which
A +. B. + C. = 180°
X. +. 40 +. 110 = 180
X + 150. = 180
X. =. 180-150
X. = 30°
hope it helps...
Angle A + Angle B = 180°
40° + x + 110° = 180°
x + 150° = 180°
x = 180°-150°
x = 30°
In triangle ABC :
x° + y° + 110° = 180°
30°+ y°+ 110°= 180°
y°+ 140° = 180°
y° = 180°-140°
y° = 40°
Alternative method to find y...
Angle DAC = y
[AC is a transversal and the two angles are interior opposite angles and thus equal]
