An = a1 * r^(n-1)
n = term to find = 18
a1 = first term = 3
r = common ratio = 4/3
now we sub
a18 = 3 * 4/3^(18 - 1)
a18 = 3 * 4/3^17
a18 = 3 * 133
a18 = 399
I'm taking you at your word. I think these sentences are true
because you said them:
-- Samuel has read 3/6 of his assignment.

Tan(58)=10/x
x=10/tan(58)
x= 6.2
Answer:
Right angles is 90° so 90°+30°=120°.A straight line is 180°. So you do 180°-120° which is 60. So A=60°
Answer:
x = 4; x = -4
Step-by-step explanation:
|3x| = 12
3x = 12
3x/3 = 12/3
x = 4
3x = -12
3x/3 = -12/3
x = -4
