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°
