Need the answer quick pls
what is the measure of angle a b d if the measure of arc b d is 130°?
a. 130
b. 100
c. 75
d. 65

m<ABD==65°

Step-by-step explanation:

we know that

1) The triangle DFB is an isosceles triangle, because

DF=BF=radius of the circle

2) BF is perpendicular to the tangent AC at point B

3) The measure of angle m<ABF=90°

4) The measure of angle m<DFB is equal to the measure of arc BD by central angle

so

m<DFB=130°

5) The measure of angle m<DBF=(180°-m<DFB)/2

so

m<DBF=(180°-130°)/2=25°

6) m<DBF+m<ABD=m<ABF

m<DBF+m<ABD=90°> complementary angles

25°+m<ABD=90°

m<ABD=90°-25°=65°
