Question

in a quadrilateral ABCD A=45°,B=135°,C=D find the masure of C​

Answer 1

Answer:

Solution given below

Step-by-step explanation:

In Quadrilateral ABCD

A=45

B=135

C=?

D=?

360-(45+135)

360-180=180

C=90

D=90

Answer 2

Answer:

answer is 90°

Step-by-step explanation:

ABCD I is an quadrilateral in which A= 45° B=135°

C=D find c

A+B+C+D = 360°

let c be x

45 + 135 + x + x =360

180+2x=360

2x=360 - 180

2x= 180

x=360/2

x= 90°

c =90°
