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°
1/2 x 3/4
1 x 3 / 2 x 4
= 3/8
S=<span>πr + πre
s=r(</span>π+πe)
r=2/π(e+1)
Answer:
44
Step-by-step explanation:
F(x)=6(8)-4
6(8)=48-4=44
Hope this helps sry if I get it wrong.
