Question

find the value of x​

Answer 1

first, By using sum angle property

30+40+y=180

70+y=180

y=180-70

y=110

so,

we know that

angle Y + angle z =180

angle z = 180-110

=70

so at last

angle Z = angle X

therefore X = 70

Answer 2

Answer:

x=70 degree

Step-by-step explanation:

in triangle angle O=110 degree

therefore x=70 degree straight line...
