Answer:
x = 60
Step-by-step explanation:
The 60° angle and angle x both have 2 marks, so they are congruent.
x = 60
So im a little confused on what you are asking here are you asking for someone to give you the rule and also do you just want to answer or how we found it?
Answer:
There are 3 angles on a straight line : WYX, WYV, VYZ
now,
given, (WYV = 6x - 12) , (VYZ = x + 16) ,
(WYX = VYZ) { They are opposite angles}
.
Sum of all the angles will be 180°
WYX + WYV + VYZ = 180°
(6x - 12) + (x + 16) + (x + 16) = 180°
6x - 12 + 2x + 32 = 180°
8x + 20 = 180°
8x = 180° - 20°
8x = 160°
x = 160°/8 = 20°
now,
put the value of 'x' in WYV i.e. (6x - 12) = (6*20 - 12) ° = (120 - 12) ° = 108°
hence, WYV = 108°

Answer:
D. 115
Step-by-step explanation:
They both are vertically opposite angles if look at them at a slight angle.
Hope it's the correct answer!
