Answer 1

Answer:

2).ta= 5

su= 12

tu= 13

sin t= 12/13

cos t = 5/13

sin u= 5/13

cos u= 12/13

tan u= 5/12

Answer 2

proof: Draw seg OD. 

∠ACB = 90°          angle inscribed in semicircle

∠ACB = 45°        CD is the bisector of ∠C

m(arc DB) = 2∠ACB =  90°     inscribed angle theorem

∠DOB = 90°      definition of measure of an arc (I)

seg OA ≅ seg OB     Radii of the circle     (II)

∴ line OD is prependicular bisector of seg AB      From (I) and (II)

∴ seg AD ≅ seg BD
