Question

find the value of x and y if a trapezium A is 80 degree ,B is 70 degree C is y and D is x
options are
A 70 ,80 degree
B 100,110 degree
C 80, 70 degree
D 110,100 degree​

Answer 1

Answer:

option (A) hope this answer will help you

Answer 2

Answer:

option D is correct.

X=100 degree, Y= 110 degree

Step-by-step explanation:

1. let a Trapezium ABCD is drawn where AB ।।CD
2. we know that the sum of two interior angles between two parallel lines at the same side of Transversal is 180 degree
3. Here angle A and B , and Angle B and C are two pairs of interior angle at the same side of AD and BC transversal respectively
4. Therefore, obviously (angle A + Angle B) = 180 degree and (Angle B + angle C)= 180 degree
5. given A = 80 degree and D = X degree therefore angle D equal to ( 180 degree- 80 degree ) = 100 degree
6. And B = 70 degree and C is = y , Y =( 180 - 70 ) degree = 110 degree .
