Question

find the measure of unknown angles​

Answer 1

Answer:

good evening

Step-by-step explanation:

x= 50 v.o.t

z= 50+z= 180 linear pair

= z= 180-50

= z= 130

y= 130 v.o.t

please mark me brainliests

Answer 2

Step-by-step explanation:

Given, 1 angle = 50°

Since, x is the vertically opposite angle of the first angle, therefore, angle x = 50°

Again, angle z and y are vertically opposite to each other,

So, they z+y = 2z(or)2y. (since, they r equal)

A/Q,

50° + x + z+ y = 360°

= 50° + 50° + 2z = 360°

= 100° + 2z = 360°

= 2z = 360°-100°

= 2z = 260°

= z = 260/2

= z = 130°

Hence ,

angle z = 130°

angle y = 130°

To check:-. (if u want to check)

50 + 50 + 130 + 130

=100+260

= 360°

thus, verified

Hope it helps (•‿•)
