In the figure, ab || cd. find x and y.
a) x=33, y=131
b) x= 53, y= 131
c) x= 37, y= 147
d) x= 131, y= 53

Given Triangle is Right angled triangle

According to Angle Sum Property,

37 +90 + x= 180

127 + x= 180

x= 180 -127

x= 53

AB//CD ( given)

<ABD= y-4 = 180-x

y-4 = 180 -53

y-4 = 127

y= 127 +4 = 131

Hence B) x= 53, y= 131

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
