Answer:
L = 50 * (-0.4)^(n - 1)
Step-by-step explanation:
r = t2/t1 = -20/50 = - 0.4
a = 50
L = 50 * (r)^(n - 1) Let's see if we can get the answer when n = 3
L=50 * (-0.4)^(3 -1)
L =50* (-0.4)^2
L = 50 * 0.16
L = 8 which is correct
The answer is Angle Y equals 138.
angle y= 180 -42 which gives u 138
Thye have to have like denominators.
So it becomes, 6/15+5/15 which is equal to 11/15
