Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°
Answer:
oh wow thx
Step-by-step explanation:
A. She would use hours to minutes, which you can do by dividing 22 by 60.
b. 22 / 60 = .366 repeating, or about .37 per minute
6=S
therefore, to find one you must divide both sides by 6
the answer should be = 1=S/6
The formula of a trapezoid is the sum of the both bases multiplied by the height then divided by 2.
