Answer:
31st term = 84
Step-by-step explanation:
Given:
204, 200,196,...
Find:
31st term
Computation:
204, 200,196,...
First term a = 204
Difference d = a3 - a2
Difference d = 196 - 200
Difference d = -4
An = a + (n-1)d
A31 = 204 + (31-1)(-4)
A31 = 204 - 120
A31 = 84
Answer:
below
Step-by-step explanation:
consecutive angles are supplementary in parallelogram
q+t = 180
3x+5+9x-17 = 180
12x-12 = 180
x-1 = 15
x=16
r=t = 127°
q=s = 53°
