Question

find x from the given figure

Answer 1

let Mark 60 as angle 1
let Mark 50 as angle 2
let Mark 20 as angle 3
let Mark 30 as angle 4
Mark 20 as angle 5
and
Mark x as 6
and take more 4 ANGLES in the figure as 7 ,8 ,9 and 10
according to question :
》 angle 1 +angle 2 +angle 7 =180 ( angle sum property )
》60+50+angle 7 =180
》110 + angle 7 =180
》 angle 7 = 180-110
= 70
now we know the value of angle 7 which is 70

angle 7 is equals to angle 9 vertically opposite ANGLES.
value of angle 9 = 70

we can find angle angle 8 with the help of a angle 7 as shown here ,
》 angle 8 +angle 7=180 ( linear pair )
》angle 8 =180 - 70
=110
110 +20 + angle 10 = 180 ( angle sum property )
130 +angle 10 =180
angle 10 =180-130
=50
● value of x :
》 70 +50 +x =180 ( angle sum property)
》x =180-120
=60
