Question

In the figure m(arc BC) = 137°
M(arc PQ) = 41°
find measure of angle BAC.
By property of=
m BAC=1/2=[ ]-[ ]
m BAC=1/2=[ ]-[ ]
m BAC =[ ]​

Answer 1

Answer:

(1) It is given that line AB is tangent to the circle at A.

∴ ∠CAB = 90º (Tangent at any point of a circle is perpendicular to the radius throught the point of contact)

Thus, the measure of ∠CAB is 90º.

Answer 2

Answer:

48 degree

Step-by-step explanation:

m angle bac =1/2[m(arc BC )- PQ]

=1/2[137-41]

=1/2×96

Therefore m angle bac = 48 degree
