Question

given ab and ad are tangent of c and the m 12 years ago

Answer 1

do you have a pic wid this q... ?

Answer 2

yeah hold on

Answer 3

ok :)

Answer 4

thats the pic

Answer 5

for any circle, a tangent makes 90 degrees with the radius

Answer 6

since BDC = 45, can you find ADB ?

Answer 7

ADB is the same as DAB isnt it

Answer 8

you can verify this with the sine law.

\[\frac{ a }{ sinA } = \frac{ b }{ sinB } = \frac{ c }{ sinC }\]

for a triangle ABC, where a is the length of the side opposite of angle A.



since BC and CD are the same length (radius of circle) their angle are are the ame implying that < BCD = < ABD = 90

Answer 9

are the same which implies that *

Answer 10

so DAB is 90

Answer 11

yes since < BCD and < BDC are 45 and the angles of a triangle sum to 180

Answer 12

thank you (:

Answer 13

glad i could help :)
