Find the m
A)50 degrees
B)60 degrees
C)70 degrees
D)80degrees

Step-by-step explanation:

∠DEC + ∠EDC + ∠ECD = 180  {angle sum property of triangle}

45 + 65 + ∠ECD = 180

110 +∠ECD = 180

∠ECD = 180 - 110

∠ECD = 70°

AB // CD and AE transversal

∠BAC = ∠ECD    {Corresponding angles are equal}

∠BAC = 70°

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
