Question

Find X Y Z and W in the figure​

Answer 1

Answer: 80

Step-by-step explanation:z+70=180

z=110

x+130=180

x=50

y+80=180

y=100

70+80+130+?=360

?=360_ 280

=80

Answer 2

in the figure​

let ∠60° = a

    ∠80°=b

    ∠120°=c

and 1st We have to find the ∠d

We know that opposite side of a quadrilateral is 180°

that is

∠a+∠c = 180°

and

∠b+∠d = 180°

∠a+∠c = 180°

∠60°+∠120° = 180

and

∠b+∠d = 180°

∠80°+∠d= 180°

∠d= 180°-80°

∠d= 100°

So we got ∠d

Now  

x=   80°

y= 60°

z= 100°

w=120°

x+y+z+w= ?

80°+60°+100°+120°=360°
