first find the nth term = -19n+5
then do -19×91+5= 1724
Answer:
18.61
Step-by-step explanation:
Principle = £4500
Time = 6yrs
Rate = n%
Simple interest = £5025
n = ?
We know,
SI =PTR/100
£5025 = £4500*6*n/100
£502500 = £27000*n
n = 18.61
Answer:
x=20
Step-by-step explanation:
First, find LJ
Angle L = 60 (180 - 30 - 90)
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos(L)=adj/hyp
cos(60)=LJ/40√2
LJ = cos(60)*40√2
LJ = 20√2
Now you can use LJ to find x. You also know the value of each angle, 45
x=20√2⋅cos(45)
x=20
