Question

ABCD is a cyclic quadrilateral in which ab is parallel to cd. if angle B is 65°, find other angles

Answer 1

Answer:

ABCD is a cyclic quadrilateral in which ab is parallel to cd. if angle B is 65°, find other angles

Step-by-step explanation:

in a cyclic quadrilateral the sum of the angles is 180 and the total angle is 360

ab is parallel to cd so the alternate angles are  equal

so if b is 65 then even a is 65

then c is 180 - 65 = 115

so  d is also 115 vertically opposite angles

D=115

A=65

C=115

Answer 2

Answer:find the ratio of LSA AND TSAof cube

Step-by-step explanation:LSA=4a sq TSA=6a sq

=4a:6a (a a cancel and multiply by2)

=2:3
