Given that two tangent lines are constructed from the shared point A outside a circle with the center O and points of tangency B
and C, what is the measure of ∠OAB if ∠OAC measures 30°?
2 answers:
Answer:
OAC =30
Step-by-step explanation:
Given that for a circle there are two tangents at points of contacts B and C meet at A
The centre of the circle is O.
By tangents theorem for circles, OAB and OAC are congruent
Hence angle OAB = angle OAC
Angle OAB is given to be 30 degrees
Hence angle OAC is equal to 30 degrees

Quadratic expression
Step-by-step explanation:
5x + 3x^2 − 7
Degree of expression = 2
So it is Quadratic expression
The answer it 1. is A.
The answer to 2. is B.
Answer is C
Because 2 is your Y intercept and -1/2 means your going to move down 1 then move 2 to the right
