Because AC is a diameter we can find the 180/3 = x
giving us the x= 60
Then that arc AB = 120
By definition of absolute value, if 
, then 
, so
On the other hand, if 
, then 
, and
Did you figure out the answer cause i need it
SinA= 16/20= 4/5=0.8 degree
cosA=12/20=3/5=0.6 degree
tanA=16/12= 4/3=1.33 degree
Answer:
B.
Step-by-step explanation:
In statement (1), we are given that m∠BAC=m∠BCA
If the two angles are congruent, this means that the sides opposite the angles are also congruent. These sides are AB and BC. Therefore:
AB=BC | B. sides opposite equal angles are equal
:Done
*The side opposite a given angle is the side towards which the angle opens up to. For example, ∠BAC opens up towards the side BC, and ∠BCA opens up towards side BA.
