Question

Use thos photo and give me answer ​

Answer 1

Answer:

Step-by-step explanation:

(a)

Sum of all interior angles of quadrilateral =360  

0

 

∴50+130+120+x=300

x=60  

0

 

(b)  

90+a=180

a=90

Sum of all angles of quad =360

x+70+60+90=360

x=140  

0

 

(c)  

70+a=180 (Linear pair)

a=110

60+b=180 (Linear pair)

b=120

Sum of measures of all angles of pentagon =540  

0

 

∴120+110+x+x+30=540

2x=280

x=140  

0

 

(d)  

Sum of all angles of pentagon 540

Given all angles are equal

∴5x=540

x=108
