A. 40°

Step-by-step explanation:

Given:

m<BEF =25°

m<B = 50°

m<ACB = 65°

Required:

m<D

SOLUTION:

m<CED = m<BEF (vertical angles theorem)

m<CED = 25° (Substitution)

m<ACB + m<DCE = 180° (linear pair theorem)

65° + m<DCE = 180° (substitution)

Subtract 65 from both sides

m<DCE = 180° - 65°

m<DCE = 115°

m<DCE + m<CED + m<D = 180° (sum of triangle)

115° + 25° + m<D = 180° (substitution)

140° + m<D = 180°

Subtract 140° from both sides

m<D = 180° - 140°

m<D = 40°

i dont know men

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
