Question

Please give the answer ​

Answer 1

Answer:

figure a

in ∆abc

a+b+c=180°. ( by angle sum property )

angle a = 180°-122°. ( by linear pair )

a = 58°

angle b = 180°-128° . ( by linear pair )

b = 52°

angle c we can easily calculate by angle sum property .

58° + 52° + c = 180°.

c = 180- 110°

c = 70°

then ,

x = 180° - 70° ( by linear pair )

x = 110°

answer of figure 2

angle a = 180° - 160°= 20° ( by linear pair )

angle c = 110°

angle b = ( 180°- a+b ) 180- 20°+110° ( by angle sum property )

b = 50°

then we can easily calculate the value of x by linear pair .

x = 180°-50°

x = 130°

i hope you get your answer .

thank you !!
