Answer 1

Answer:

angle C=36°

angle y=50°

angle X=130°

angle Z=130°

Answer 2

Answer:

for fig 3

answer is 126

Step-by-step explanation:

proof ,

2:3=b=90degree

2x+3x=90degree

5x=90degree

x=18

so,2x=36

3x=54=b=O(verticle interior angle)

so,angle xcn+yon=180 degree

xcn+54=180 degree

(xcn=c) c=180-54

c=126 degree
