Answer 1

Answer:

m< CDF = 36

Step-by-step explanation:

m< CDE =m< CDF + m< FDE

120 = m< CDF + 84

m< CDF = 120 - 84

m< CDF = 36

I hope I helped you^_^

Answer 2

Answer:

CDF is 36°.

Step-by-step explanation:

Since CDE or the whole measure is 120° and FDE is 84°.

We have to find the value of CDF that combines with FDE and get 120°.

Let CDF = x, FDE = 84° and CDE = 120°. Therefore, the sum of CDF and FDE is the whole measure or CDE.

x+84=120

Subtract both sides.

x+84-84=120-84

x=36.
