Step-by-step explanation:
The last option. would be correct
First of all do you know any formulas for are of a circle the circumference etc
Answer:
x = 115° , y = 65° , z = 115°
Step-by-step explanation:
x and 65° are a linear pair and sum to 180°
x + 65° = 180° ( subtract 65° from both sides )
x = 115°
y and 65° are vertically opposite angles and are congruent , then
y = 65°
x and z are vertically opposite angles and are congruent , then
z = x = 115°
