Question

. ABCD is a quadrilateral in which AD || BC. If a= 110° and d= 130°, what are the
measures of the other two angles?​

Answer 1

Answer:

Step-by-step ABCD is a concyclic quadrilateral and also that angle A=110 and angle d=130

so, we know that opposite angles in a concyclic quadrilateral forms supplementary angles

so Angle A has angle C as its opposite

so, Angle C=A+C=180

110+C=180

C=180-110

C=70

now, angle B is opposite to angle D

so D+B=180

130+B=180

B=180-130

B=50

SO C=70 AND B=50

Answer ♡

Step-by-step explanation:

$angleb = 70$

$angle \: c = 50$
