Answer:
137°
Step-by-step explanation:
Basically, its the reverse of question 1.

the angle is twice the size of angle y as said in the corcle theorems.
254 divided by 2 = 137°
(please correct me if im wrong, i feel like im missing something)
Answer:
10 sqrt(3)/3 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side /adj side
tan 30 = x/10
10 tan 30 =x
10 ( sqrt(3)/3) = x
10 sqrt(3)/3 =x
