6a-(n-1)(3a) is the nth term
Expanding we get 6a-3an+3a=9a-3an=3a(3-n)
SOLUTION: nth term is 3a(3-n)
The answer is 90°
The sum of all angle in a triangle is 180°
So,
180-(45+45)
= 180-90
= 90°
3+5=8
Answer:
2/8
Step-by-step explanation:
probability = total number of items ÷2
=8÷2
=2/£
= 5.45 × 1.5/0.025
= 5.45 x 60
= 327
Answer= 327
Hope this helps! :)
Answer:
10
Step-by-step explanation:
10x²-14x+k = 0
x1 = sin a
x2= cos a
x1+x2 ≤ 2
x1. x2 ≤ 1 => k/10 ≤ 1
k ≤ 10
so the value of k should be 10
