Answer:?
Step-by-step explanation:
The explicit formula would be
This is a geometric sequence, since each term is found by multiplying the previous term by a constant. The explicit form of a geometric sequence is given by
where r is the common ratio, or constant we multiply by, and g₁ is the first term. For our sequence, g₁ = 5 and r = 3, so our formula is
Answer:
x=15
Step-by-step explanation:
the basic property is: AB/AD=BC/CD, for more info see the attachment.
Answer:
There are 3 angles on a straight line : WYX, WYV, VYZ
now,
given, (WYV = 6x - 12) , (VYZ = x + 16) ,
(WYX = VYZ) { They are opposite angles}
.
Sum of all the angles will be 180°
WYX + WYV + VYZ = 180°
(6x - 12) + (x + 16) + (x + 16) = 180°
6x - 12 + 2x + 32 = 180°
8x + 20 = 180°
8x = 180° - 20°
8x = 160°
x = 160°/8 = 20°
now,
put the value of 'x' in WYV i.e. (6x - 12) = (6*20 - 12) ° = (120 - 12) ° = 108°
hence, WYV = 108°
