Good evening ,
Answer:
An = 8×(5/2)ⁿ⁻¹
Step-by-step explanation:
An = A1 × qⁿ⁻¹
A1=8 and q = 20/8 = 5/2
then An = 8×(5/2)ⁿ⁻¹.

Answer:
m∠E=57°
Step-by-step explanation:
∠FDE=∠FED=(4x+1)° (base angles of isos triangle)
2(4x+1)+(5x-4)=180 (angle sum of triangle)
8x+2+5x-4=180
13x-2=180
13x=180+2
=182
x=182÷13
=14
Hence, m∠E = (4x+1)°
= [4(14)+1]°
= (56+1)°
= 57°
They’re adjacent angles, they share a same side. And complementary angles because they add to 90
