Answer:

4) The smallest angle is A) 40

5) The answer is C) 115

Step-by-step explanation:

5) CD bisects ACB

So ACD = DCB

3x-2 = 5x-20

3x-5x = -20+2

-2x = -18

x = 9


ACD = DCB = 25°

All angles in a triangle are equal to 180°

CD ⊥ AB

So CDB right triangle

∠DBC = ??

180-(90+25)

180-115 = 65°

∠CBF = 180°

∠DBF = 180-65 = C) 115°
