Answer:
-2
Step-by-step explanation:
4x=4-12
4x=-8
X=-2
And answer is - 2
The answer is 1.72 and if you estimate it then about 2 or 1.75
B=7h-2
When h=14 b=96
a=(1/2)b*h
Therefor a=(96*14)/2
a=672cm^2
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°
