The angles are 72 degrees and 108 degrees.
Explanation:
Angle 1 : Angle 2 = 2 : 3
Angle 1 = 2k
Angle 2 = 3k
Angle 1 + Angle 2 = 180 (supplementary angles)
2k + 3k = 180
5k = 180
k = 36
Angle 1 = 2k = 2 x 36 = 72 degrees
Angle 2 = 3k = 3 x 36 = 108 degrees

Answer:
a(6)=2430
Step-by-step explanation:
a(1)=10
a(n)=3×a(n-1)
This is a geometric sequence, with ratio=3
a(2)=3×a(1)=3×10
a(3)=3×a(2)=3²×10
a(6)=3⁵×20=(27×9)×10=243×10=2430
